The header bar flashes on resize when the filename is too large to be shown on the header bar

[Naiara Gomez Castro]

I recently installed the app from Flathub, and when I click the "New document" button, I get the editor in the narrow mode, and if I try to resize it, the header bar start flashing and changing between two modes. I noticed it happens 'cause the default filename is too large. If I save the file with a shorter name and open it again, the issue is fixed.

Version: 3.0.0 (from Flathub)

I attach a screencast.

Fixed, next version (3.1.2) should have the fix.
