Prerequisites

• I verified that this is not a filter list issue. Report any issues with filter lists or broken website functionality in the uAssets issue tracker.
• This is not a support issue or a question. For any support, questions or help, visit /r/uBlockOrigin.
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue.
• The issue is not present after disabling uBO in the browser.
• I checked the documentation to understand that the issue I am reporting is not normal behavior.

I tried to reproduce the issue when...

• uBO is the only extension.
• uBO uses default lists and settings.
• using a new, unmodified browser profile.

Description

:has-text doesn´t work inside :is OR :where

Element picker doesn´t select as expected (1.44.5b15).
In latest stable version (1.44.4) the Element Picker shows an error with the formula provided in the next steps.

In case there is a similar issue, I coldn´t see it really as :is() :where() are conflictive terms to search.

Edit: I just want to make it clear that this does not work under either Element Picker or My Filters section.

A specific URL where the issue occurs.

https://github.com/uBlockOrigin/uBlock-issues/issues

Steps to Reproduce

1. Go to https://github.com/uBlockOrigin/uBlock-issues/issues
2. Open Element Picker and add: ##:is(.open.octicon,.IssueLabel:has-text(enhancement)):others()
3. Note: You can also check this formula, that works perfectly without :has-text():
   ##:is(.open.octicon,.IssueLabel):others()

Expected behavior

Everything except Open Issue Icons and Enhancement Labels should be selected.

Actual behavior

Nothing is selected

uBO version

1.44.5b15

:is() and :where() are not pseudo operators, they can't have pseudo operators as parameters -- so the issue here is a feature request, not a bug.

Given the case provided is contrived, i.e. not a real case world demonstrating this is needed, the incentive to make this work is close to zero.

[Vanerio]

Well, this particular case is contrived because it pretended to be easy to test.
I discovered this while trying to make a productive task: showing in page only threads that matches x:has-text() that are unread or if I received a PM. Or only show emails that are from x|y|z persons and have an important tag.

Using :others() for me saves a lot of time and makes my interface a lot of cleaner. I have been using this a lot, but this is the first time I needed a :has-text() match. So for me this totally makes sense in a real case world scenario where performance and minimalism is pursued.

I would be really thankful if this could be added in case it is not a very difficult task. I hope I could help you with that programming part, but I am not a programmer. In any case,, I would like to thank you for your amazing work.

Here I show you how I clean my interface to enhace performance. It is a real example: I remove every part I don´t need and I only show unread threads and notifications (with just a simple line). I don´t know if this is a real case scenario to be honest, For me it is actually and uBlock helps me a lot doing that and increases efficiency in my work by keeping my interface straighforward. This is a really big forum simplified into 5 items.

There are other cases where has-text() would help me to be a lot more precise by adding a powerful filter.

Well given your case in opening comment, I would just suggest to use:

##.IssueLabel:has-text(enhancement):upward(.js-issue-row):others()

I am pretty sure I could come up with something equivalent for your specific case if I knew the details.

Well given your case in opening comment, I would just suggest to use:

##.IssueLabel:has-text(enhancement):upward(.js-issue-row):others()

This works perfect if you only need to isolate rows, but the thing is, if you need to isolate not only rows, but, lets say, also .js-feature-preview-indicator-container , you can not combine them (with :is or :where) because of :has-text()
Like in my example, where I try to isolate two different things.
Example isolating just 3 things::
##:is(.unread:has-text(xxx|yy|zzz), .notifications, .action-bar):others()

Edit: Another real example for me (maybe i'm using uBlock for things it wasn't supposed to be used for? haha)
This is how my outlook looks like. I isolate unread emails and two buttons. Thats it. The case is that in other scenarios :has-text() would be needed.
