on scaled monitor
Classification: Plasma
Product: kwin
Version First 6.5.4

Firefox log file (MOZ_LOG="timestamp,WidgetPopup:5" MOZ_LOG_FILE="popup").
SUMMARY
The position of the drop down menu is in the wrong position, when following the
steps on the scaled monitor.
I initially reported this on the Firefox bug tracker
(https://bugzilla.mozilla.org/show_bug.cgi?id=2005452), but I was told to
report it against KWin instead.
Video showcase: https://bug2005452.bmoattachments.org/attachment.cgi?id=9532634
STEPS TO REPRODUCE
Monitor setup:
- Primary monitor (2560x1440, 100% scaling).
- Secondary monitor (2160x3840, 150% scaling).
1. Open Firefox and move the window to the scaled monitor.
2. Create a folder in Bookmarks Toolbar.
3. Create another folder, within the newly created folder.
4. Populate that folder with a couple bookmarks.
5. Move Firefox to the second monitor. (150% scaling)
6. Open the nested folder.
OBSERVED RESULT
The position of the drop down menu is in the wrong position, when following the
steps on the scaled monitor.
EXPECTED RESULT
It should behave like the non-scaled monitor.
