commit 532ae0ac0c800f856719ecf616db5e20e5749553
Author: Qiu Wenbo <qiuwenbo kylinos com cn>
Date: Sun Aug 22 23:40:48 2021 +0800
ev-view: bring back keybinding for scroll and caret mode.
The order of the shortcuts callback being called is not guranteed. So we
should guard the scroll handler from claiming the event. Also, we should
make the scroll handler to return a boolean to claim the event and keep
the parent window from calling the move focus callback.
