SUMMARY
When using the Breeze Dark theme and using KSystemLog, all items in the menu bar are invisible. Some toolbar item icons are invisible. Almost all toolbar item text is invisible.

STEPS TO REPRODUCE
1. Open System Settings
2. Change Global Theme to Breeze Dark
3. Open KSystemLog
4. Enter password
5. KSystemLog opens with theme not correctly followed

OBSERVED RESULT
All menu bar items are invisible, unless hovering cursor over items. The Stop and Refresh log tool bar icons are invisible, unless hovering cursor over them. All toolbar item text is invisible, apart from Details. All other visible elements follow the theme correctly.

EXPECTED RESULT
All menu bar and toolbar items should be easily viewable when using a built-in theme.
