Fixes

  • Renders chat header dropdown popovers through a body portal so they are not clipped by the chat window.
  • Keeps dropdowns inside viewport edges, including constrained bottom/right positions.
  • Adds ARIA linkage between dropdown trigger and portaled listbox.
  • Includes e2e coverage for viewport-edge dropdown positioning.

Verification

  • GitHub PR #262 merged after required checks passed: test, e2e, e2e-install, review, CodeRabbit.
  • Local verification: npm test passed 119/119 files and 1429/1429 tests; chat-popup Playwright spec passed 4/4.
