Editor repeating tailing character instead of pressed one

[mlewand]

After some typing (some text, 1 link, 1 emoji no undos or anything like that) the editor started to repeat only the last character, despite the fact that I was pressing different printable characters.

It was just substituting the pressed key with character that was a last character in existing content and appending it (in my initial case that was simply empty space).

Happened for the following data (so you can see not much formatting):

Funny thing that as I started to record GIF for this I discovered that it repeats tailing character rather than doing only non breaking spaces (as opposed to what I initially thought).

Here's the screencast (I was mashing random keys but the editor kept repeating last letter):

The console is clean, there's no bleeding there.

I know that this is yet another kind of an issue like "xyz" happens when using the product, but I really don't have more repro data on that (though it's the first time I see this issue for a long time).

It sounds like an upstream issue to CKEditor 5, but I'll mark this one for waiting for more information, because I'm afraid we have little to do here without reproducible steps :(

Sounds pretty much like ckeditor/ckeditor5#6495 and it looks like we're going to resolve this in the upcoming iteration.

The issue mentioned by @mlewand was resolved so the next release of CKE5 will ship a patch for it.

This issue should have been fixed with the recent upgrade to CKEditor 5 v19.0.0.
