  # Frontend tests with the same /ether plugin set that backend-tests.yml
  # exercises, so a core change that breaks plugin UX is caught in PR CI
  # rather than after release. Re-introduces coverage that was lost when
  # the workflows were nuked & rebuilt in 2023 (commit cc80db2d3) and the
  # backend equivalent was restored without the frontend half.

        # ep_cursortrace's `aceEditEvent` hook fires on every keyboard
        # event (handleClick, handleKeyEvent, idleWorkTimer) and sends a
        # cursor-position socket message per call. Under the test
        # harness's `writeToPad` bursts (insertText + Enter loops) that
        # stream of socket messages saturates the editor's input
        # pipeline in Firefox specifically, causing intermittent
        # keystroke drops and a long tail of test flakiness.
