Custom Expression Text Field issues with Firefox

The text field for custom expressions is broken on firefox. It has a offset by 1 char, so it becomes very confusing when you want to remove or change values. Made a little screencap. I tried to change the 1 to 2:
custom-expression-firefox

System: Windows 10, Firefox 108.0.1.
It doesn't happend on chrome on the same pc.
