<title>CSS Basic User Interface Test: interacting with the ellipsis</title>

<meta name="assert" content="Pointer events on the ellipsis should be dispatched to the elided inline element if there's one, rather than directly to the block.">
<!-- This is tested indirectly, using elementFromPoint instead of actually triggering a pointer event, because:
  * Actual pointer events can only be dispatched in an manual test, while elementFromPoint allows for an automated test
  * These two methods are expected to give the same result

  This indirection and the slight risk of false positive or false negative it introduces
  is preferable to a manual test which would hardly anyone would ever run.
