does not seem to work right still - if you arrange the split panes to make the emoji wrap (see the next screenshot), I think not only it shows incorrect insertion index when you move the mouse across that emoji (in Text.hitTest goes from 0 to 1, while expected change is 2), but I think it's also wrong because that emoji is the last symbol in that Text instance, so insertion index should be different (larger).
Are you reporting insertion index relative to the Text's text or TextRun?
