(Still wondering if maybe this should be renamed to GetLeadingBubbleAnchorView()
or something?)

[tapted, 2017/02/24 02:01:24]

If it's OK, I might defer the rename.. Someone might want this merged to m57
(same as r449119). Also our designer might decide the first run bubble needs an
arrow.. (Plus, how would we pronounce "leading"? :)

[Peter Kasting, 2017/02/24 02:05:16]

Ha!  I'm pretty sure THIS one, at least, I know how to pronounce.
