1299215 - [Pointer Events] Decouple `button` and `buttons` when synthesizing Widget Events.

Status: RESOLVED DUPLICATE of bug 1292070

(Core :: DOM: Events, defect, P2)

Description

[Ben Hsu [:HoPang]]

Pointer Events carry both `button` and `buttons` attributes, where `button` represent the button triggering the event, while `buttons` represent the button state combination of the input device when the event is triggered. Now, the value of `buttons` is always computed from `button`[0] passed into the test automation API. Doing this way, we are not able to synthesize an input device with multiple buttons pressed, and thus cannot test related features.

Hi Ben, if I understand your plan correctly, this is something we aim at by the end of this quarter. So, I mark it as P2, i.e. in the next release/few months. Let me know if I misunderstand the plan. Thanks!

Thanks Ming-Chou for his work, it seems he did a pretty good jib here :)
