Research direction
Investigate the dark mode implementation in PR #11857, focusing on TreeView and ListView editing logic. Look at the source files for TreeView and ListView in the repository, specifically the parts handling label editing and dark mode color schemes. Check comments on the issue for any maintainer guidance. Compare the dark mode behavior for non editing nodes versus editing nodes to identify missing color overrides.
