Code review comment for lp:~nick-dedekind/unity8/side-stage-redesign

About the TouchRegistry change: Please write a regression test to cover this fix and please also propose it to the TouchRegistry copy in ubuntu-ui-toolkit. We will soon move to use it (s/DirectionalDragArea/SwipeArea) so we will need the fix there as well.

I feared such reentrancy issues and was considering s/sendEvent/postEvent throughout TouchRegistry because of that, but ended up never doing so...
