1896402 - The coordinate of click event in parent process might be incorrect

Status: RESOLVED FIXED

(Core :: DOM: Events, defect)

Description

[Edgar Chen [:edgar] (Parental leave until Oct. 09.)]

The click event is generated from mouse up event in https://searchfox.org/mozilla-central/rev/ee2ad260c25310a9fbf96031de05bbc0e94394cc/dom/events/EventStateManager.cpp#3855. It happens after the mouseup event has been dispatched to the content process, which transforms the coordinate to the content process's coordinate space. So we end up using transformed coordinate to generate click event in parent process.

to avoid using the transformed coordinate in parent process after the event has
been dispatched to the child process, e.g. when generating a click event.
