Subject: [PATCH] fix(frontend): mention popover respects shouldBelow for
 above/below placement
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ShouldBelow was computed but ignored — popover always rendered below the
cursor. Now uses shouldBelow correctly to render above when insufficient
space below. Also removes unused cRect clone measurement.
