VSCode "View Problem" Dialog Background Property
I searched through the VSCode Docs, but was unable to locate any useful documentation that explained what the properties that highlight the background colors for the widget demonstrated in the image below.
What VSCode Theme property modifies the "View Problem" dialogue's background color?
After two hours of isolating individual properties and trying to diagnose the issue, I can confirm that the property that controls the background color of VSCode's "View Problem" dialog is called: 'editorMarkerNavigation.background'.
I hope this helps others in the future.
