Public bug reported:

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:
