firefox 60.4.0esr (64 bits)

Confirmed in 65.0. This is pretty serious actually. The arrow keys movement is also locked after moving the selection somewhere else after inserting the link. The URL input preview (?) is also displayed like the focus never left the balloon.

Is it a regression?

[oleq]

Same in 11.1.1.

Disabling autocomplete for the link input solves the issue but it's a workaround, not a fix.
It could be an FF issue, I'll prepare a sample with input and editable out of CKE5 to check this out.

FF has some problems with blur when focused element is removed from DOM (https://github.com/ckeditor/ckeditor5-link/issues/193).

[oskarwrobel]

It's possible to reproduce this issue outside of the CKE5. When focused input is removed from the DOM then focus partially stays in this removed input?! When there is an autocomplete it takes control over the arrow keys. I'm afraid it won't be possible to fix it without some hacks.

It turns out the fix is very simple. All we need to do is blur the input (focus the other element) before removing it.

We should fix it also for the ImageTextAlternative balloon.
