Version: Adobe Indesign 2025 (20.0)
The probled occured in a file that works perfectly in Indesign 19.5. However, when I open the same file in 20.0, the error occurs.

Problem: When I try to edit text on a black background, the selected words aren't highlighted. It happens on some pages but not all. The layers aren't locked.

How to reproduce:
- create a master page with a black background
- create several pages
- add text boxes with white text in it
- try to select the text inside the box

Expected result:
- selected text is highlighted in white

Actual result:
- on some pages, the text highlight isn't visible (although it is actually selected)
