Program cannot clean text formatting.

Is there an existing issue for this?

• I have searched the existing issues

Can the issue be reproduced with the default theme (daylight/midnight)?

• I was able to reproduce the issue with the default theme

Could the issue be due to extensions?

• I've ruled out the possibility that the extension is causing the problem.

Describe the problem

When creating text with font and background color, the program can no longer clear the formatting using the floating menu that appears over the text. Version 2.12.0 is normal! But version 2.12.1 and 2.12.2 have this defect.
