Subject: eventcontrollerscroll: Events are unhandled by default
X-Git-Tag: archive/raspbian/4.4.1+ds1-2+rpi1^2~18^2~20^2~828
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=7ce1055656499b746538c46a56ee4d64c5f3ae10;p=gtk4.git

eventcontrollerscroll: Events are unhandled by default

While the ::scroll signal always returns whether it handled the event,
the others do not, for example ::decelerate.

Previously, this caused the event to stop at a scroll controller with
CAPTURE phase, never emitting the ::decelerate signal on later
controllers with BUBBLE phase.

Fixes #2151
