here is a kind of similar problem to Pasted text gets cut off.
- Standard unzip (v25.50.0202)
- Create new directory
- ==> Directory "New Folder" is editable and whole text is selected
- Enter "a"
- ==> Directory name "a" is displayed correctly
- Enter "b" (at cursor position, at the end), text field contains "ab"
- ==> Character "a" is shifted some pixels to the left (out of view)
