# Open any project with Light Mode set as theme for the Editor
# Create a UI Document Asset in the Project Browser and open it
# Enter a random string in the Libraries search text field
# Select "Project" in the Library panel

Actual results: There's a color mismatch in the Library panel between the "Project" and "Standard" Library modes when the Editor is in Light Mode

Expected results: No color mismatches, behavior the same as in Dark Mode
