Style combo box doesn't change theme

Component: Bottom Statusbar

Style combo box in the status bar changes the Style, but doesn't change the Style Theme. 

Selecting any complex theme like "Universal Dark" sets only Style to "Universal", but ignores selected "Dark", "Light", "System" Theme settings.

the resulting .conf file would contain:

[Controls]
Style=Universal

Instead it should contain something like this: 
[Controls]
Style=Universal

[Universal]
Theme=Dark
