Emulating mobile fullscreen in DevTools makes the true browser window go fullscreen, and changes emulated device screen size

Reported by teo8...@gmail.com, Jul 17 2016

Issue description

UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.106 Safari/537.36

Steps to reproduce the problem:
1. open Developer Tools and switch on mobile emulation
2. visit http://output.jsbin.com/mepame
3. click on the video's fullscreen button

What is the expected behavior?
The video should go fullscreen in the emulated device screen, which should not change its size.
Chrome's true window should not go fullscreen

What went wrong?
Not only the video goes fullscreen in the emulated mobile screen as expected, but also Chrome itself goes fullscreen, which is ridiculous and unnecessary, and what is worse is that this causes the emulated device screen to grow in height if it is in "responsive" mode.

See a screenshot of before and after clicking the video's fullscreen button. What you see in the screenshots is my entire desktop screen.

Did this work before? N/A 

Chrome version: 51.0.2704.106  Channel: stable
OS Version: 
Flash Version: Shockwave Flash 22.0 r0

Just to be clear, this is how it should look like

Tested the issue on Windows 7, Mac 10.11.5, Ubuntu 14.04 using 51.0.2704.106, canary 54.0.2799.0 as per above steps.Observed that the video goes fullscreen in the emulated mobile screen and also Chrome itself also goes fullscreen. Observed the same behavior in firefox.

Please find attached screencast and update if anything missed here in triaging the issue.

teo8976@Could you please provide actual and expected behavior screencast for further triaging the issue.

Yes, you are observing exactly the behavior that I described and that can be seen in my screenshot: you ARE observing the issue.

Isn't it obvious to you that this is not the expected behavior?? Why should Chrome itself go fullscreen?

I provided screenshots of both observed and expected behavior. Do you really need to see the mouse cursor moving to understand them?


> Observed the same behavior in firefox.

Maybe. That doesn't make it the expected behavior when it obviously isn't.

Why archived?? (what does that even mean btw?)

The issue still exists.
Archived means there is no plan to address this issue in the near future due to lower priority than other issues.
