Steps to Reproduce:

1. Create a TreeView with an TreeItem
2. Set the TreeItem's iconPath to new vscode.ThemeIcon("debug-stackframe", new vscode.ThemeColor("icon.foreground"))
3. Run the extension. The TreeItem's icon will still be yellow same as in debugging.

After inspecting developer tools, this is likely due to how the icon debug-stackframe's color rule is set to !important. The ThemeColor fails to overwrite it due to low specificity.

This may not only happen with the icon "debug-stackframe" and is affecting customisations of treeitems. Why is some icons' color rules given the !important flag et al? There might not be any easy fix due to this flag's present. I hope the team could look into it, and if possible fix this selector specificity issue (if it won't break vscode, somehow).
