Subject: button: Improve accessible setup
X-Git-Tag: archive/raspbian/4.12.3+ds-1+rpi1~1^2^2^2~22^2~1^2~160^2~2
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=cf30a4f30454dce47148b17eedd60dcb231ad768;p=gtk4.git

button: Improve accessible setup

With the current approach, we get duplicate labels
in the accessible name: _Cancel Cancel. Change things
around to always set the labelled-by accessible relation
if we have a label, and not the label accessible property.
