[artful] Opening an application from dock sometimes causes freezes followed by dock redraw

[Dmitrii Shcherbakov]

Just opened http://gnomepomodoro.org/ app. CPU spiked (judging by my laptop's fans) and I got a partial UI freeze for about a second or so followed by a dock redraw.

Multiple app open/close sequences do not seem to trigger that but I had this a couple of times already. Not sure this is dash-specific but there were several references to dash-item-container in the log after the event:
