Problem with source hover popup and Dark theme

[bgx90]

I am using the AngularJS plugin with Eclipse Neon.2. The plugin seems to be overriding the source hover popup color settings somehow, and I cannot find a way to change the background or foreground color of the source hover popups. If I set my workspace to use the Eclipse Dark theme, the AngularJS documentation in the popups that appear when hovering over JavaScript methods, objects, etc. appear as black text on a dark gray background; this is unreadable. When I change the theme back to Classic, the documentation in the hover popups still appears as black text on a dark gray background. Changing the setting in Window -> Preferences -> JavaScript -> Editors ->source hover background has no effect. Changing the setting in Window -> Preferences -> General -> Appearance -> Colors and Fonts -> JavaScript -> JavaScript Documentation view background also has no effect. These settings also have no effect if I leave the workspace set to use the Classic theme and never change to the Dark theme. If I keep the theme set to Classic, the popups are the default yellow background with black text. I prefer to use Eclipse's Dark theme. Is there some way I can configure the colors the AngularJS plugin is using for documentation popups?
