Strange, unpredictable backspace behavior; causes words to merge

[Andoriax]

I notice this occurring at random most often in the Proton email client/app where I type most frequently, though I believe it occurs in various other text fields.
I'll have to give it more attention to identify specific locations and any behavioral patterns within specific environmental contexts.

To Reproduce
Steps to reproduce the behavior:

Perhaps investigate with a Pixel with GrapheneOS and without.

1. Go to Proton email
2. Submit text into a text field such as a new email or a reply email
3. Begin to backspace each letter of each word
4. Notice the space before the current word being edited will be removed before the word is entirely deleted, thus causing the current partial-word to merge into the previous word.
5. Continue to backspace letter by letter to observe recurrences at each word.

Screenshots
Screen recording provided below.

**Smartphone

• Device: Pixel 7 Pro
• OS: Graphene
• Android Version: 14 and prior with 13

Additional context

• OpenBoard app version is up to date as current.

• Issue has been ongoing since at least Android 13 and still into 14.

• Issue may be particular to specific apps, web apps, websites, web portals. Issue is not ubiquitous everywhere, only specific or else random applications. I'll update this with any observable patterns or commonalities pertaining to usage sites in case that proves relevant.

• I suspect this as a compatibility issue involving Graphene in combination with incompatible/discriminative/underdeveloped apps/web portals, but that's just a guess.

• Issue may/may not reproduce according to content size within a text field, such as amidst 1000+ words or so, maybe not.

• Issue may/may not reproduce amidst maximized memory usage; inanely excessive internet tabs + dozens of open apps + media apps running in background + 1k—2k+ words in a text field.

I don't think this is specific to OpenBoard.

Currently I'm still using the default OASP keyboard, and have the same issue. Not in all apps thought. Just some.

For me this happens a lot in the ChatGPT app. Also with shorter texts

What OS are you running?

Chipping in to +1 this, I have it happening on my Samsung S24+ with 1.4.5 although its by no means recently introduced having been an issue I've had for a while.
