Blocks can still be inserted from the list next to the inserter even if useOnce is true

[fastlinemedia]

Issue Overview

I've created a block and set useOnce to true, however I'm still able to insert it when it shows up in the quick links next to the inserter. Notice in the screenshot below how my Test Block is greyed out in the actual inserter but can still be highlighted and clicked in the quick links.

Steps to Reproduce (for bugs)

1. Create a block with useOnce set to true.
2. Use the block enough times that it shows up in the quick links.
3. You can insert it more than once using the quick links even though useOnce is true.

Expected Behavior

You should be able to only insert the block once.

Current Behavior

You can insert the block more than once.

I guess we should check the "autocompleter" as well.

Fixed in #3988

It seems like this issue has been reintroduced at some point. The code from #3988 does no longer exist, see https://github.com/WordPress/gutenberg/blob/63abd32d9b5cb809ad71167f209dd7a6d0a79a3f/editor/components/inserter-with-shortcuts/index.js

@youknowriad Yep, it's also not disabled in the autocompleter.

Thanks to #7166, disabled blocks can no longer be inserted from the autocompleter. However, the frecent block inserter buttons still let you insert disabled blocks, though there is now an error message shown when you do so:

Can't reproduce anymore, issue seems to be fixed.

@Soean I can still reproduce in master.
