Bug ID: 498869
Summary: Keyboard focus seems to be invisible on most settings
and rendering with e.g. black on dark gray for others,
making navigation nearly impossible without a mouse

Screenshot with annotations illustrating the affected areas where keyboard
focus seems to misbehave
SUMMARY
When using the builtin Windows 9x theme of KDE and a dark color scheme, it
seems to be that 50%+ of elements in the KDE system settings don't render any
sort of keyboard focus at all, requiring to press tab followed by space or
arrow keys to mess around until something reacts and you figure out what is
focused. Some other elements seem to render the keyboard focus using a wrong
color, using black on dark gray rather than white. Only the search box seems to
work as intended. While this could be blamed on the theme, most popup dialogs
seem to have a perfectly working white on dark gray and easy to see keyboard
focus on all the buttons, so this seems to be some KDE system settings problem.
However, e.g. Spectacle is also affected.
STEPS TO REPRODUCE
1. Choose builtin 9x theme for application style
2. Choose Materia Manjaro Dark High contrast as Colors style
3. Check the regular settings UI in systemsettings for keyboard focus behavior,
and compare to any popup dialogs like e.g. the "Pair New Device" dialog in
bluetooth settings where it works as intended
OBSERVED RESULT
In most settings panes, the keyboard focus doesn't seem to be working as
intended. It's either not visible at all, or barely visible with wrong colors.
In the popup dialogs however it works, suggesting that the color theme was
meant to have a proper focus color set. Also, when I try other dark color
styles, the problem seems to persist.
EXPECTED RESULT
Keyboard focus works directly with dark color styles combined with the builtin
9x application style.
