Contributor guide

Research direction
Investigate the toolbar rendering logic in the Firefox iOS codebase, particularly in the Reader Mode integration. Look for recent commits or changes related to the toolbar redesign (FXIOS 12204) that may have introduced the flickering. Check the assignee's linked branches or Jira task for clues. The bug is likely caused by a race condition or missing state update when toggling Reader Mode.
