Project Explorer / Database Navigator folder tree font size

[9kingdom]

Since I use 4K monitor I had to change some font settings in sql editor end result table. It worked flawlessly but when I tried to do the same in project explorer or database navigator nothing has changed although I have tried all settings available in View and Editor Folders section and tried a bunch of other sections. Same goes for changing background colors. With dark theme active once you select any folder/connection etc. font color changes to black which makes it invisible on dark background. Could not found anything in official docs on the subject therefore I would appreciate any hints on how to change font size and background color of project explorer/database navigator folder tree.
Thanks.
