Subject: dash: Ignore hiding items in _adjustIconSize()
X-Git-Tag: archive/raspbian/50.5-1+rpi1~1^2~1013^2^2~7440
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=790b9d3371289300ed66b8b19879f802c64ac050;p=gnome-shell.git

dash: Ignore hiding items in _adjustIconSize()

Rather than relying on the caller to hide the remove target and
removed items before calling _adjustIconSize(), move that logic
into _adjustIconSize() itself.
