Text color in entry mixed up with placeholder text color
With some themes the text color in entries (QLineEdit) seems to be mixed up with the text color of placeholders.
This can be seen for example in the "Jump To Track" dialog in Qmmp.
Here the placeholder text "Filter" should be gray and the actual input "Hello World" should be black.
Affected themes:
- Arc
- Yaru (the default theme of Ubuntu)
- and others probably as well
Tested with qt6gtk2 0.4 and Qt 6.9 but occurs also with older versions.
