Comment 4 for bug 1725384

Are the following bugs related to this one?
Perhaps these bugs are different manifestations of the same underlying problem?..

If the dock receives two events, or responds twice to each event, then the Applications "dash" would seem to not appear when you touch the applications grid icon/button, because the applications dash would be quickly shown and unshown.

Here are examples of this "double" response , which seems to be limited to touch-screen interfaces:

Bug #1730281
"Application icons appear and suddenly disappear when Applications Button is activated via a touchscreen"

Bug #1705689
"When adding an app to favourites, two icons are created"

Bug # ???
I also noted that touching on an application in the dock opens two instances of the application.
I haven't seen if a bug report has been filed for this issue yet, but it would be additional evidence for my theory.
