1327601 - Object2VR studio doesn't know when DOM fullscreen transition ends, so demo twitched right before transition

Status: RESOLVED WORKSFORME

(Web Compatibility :: Site Reports, defect)

Description

[arni2033]

>>>   My Info:   Win7_64, Nightly 49, 32bit, ID 20160526082509
STR_1:
1. Open https://ggnome.com/object2vr/examples/rocket
2. Click fullscreen button inside the demo to switch to DOM fullscreen
3. Click fullscreen button inside the demo to switch from DOM fullscreen to normal mode

AR:
 Steps 2 - the demo expands to the whole content area, and only after that transition starts
 Steps 3 - the demo becomes very small and teleports to the top-left, and only then transition starts
ER:
 Fullscreen transition should start w/o any twitching/flickering on the page.
 For example, it should use 'fullscreenchange' event to resize <canvas> element

Note:
 When I discovered 'fullscreenchange' event, this report was already written. Originally, I thought
 that it's a Firefox bug and mentioned in possible expectations that Firefox should fire some event
 to let web pages know that fullscreen transition is finished. As it appears, there's already an event

This is working as expected now.
