Topic: Fullscreen breaks YouTube fullscreen in Android Chrome [SOLVED]

Our QA has been reporting this issue and discovered its an issue with Juicebox gallery affecting the fullscreen functionality of the YouTube video players in the same page.

I factored out that issue that any javascript code introduced in our pages is causing it.
I did that by embeding a youtube player in any of the Juicebox gallery pages (ie https://juicebox.net/demos/pro/embedded/#) and running similar steps below.

This occurs in the Android devices that our QA team tested but this can be reproduced also using Chrome's simulator for mobile devices
1) Open Chrome > Tools > More Tools > Developer Tools
2) Click 'Toogle Device Toolbar' icon (top left of developer tools)
3) Select 'Nexus 7'
4) Visit https://www.warnerbros.com/justice-league/photos and click a thumb to expand gallery (or go directly to https://www.warnerbros.com/justice-leag … #expanded)
4) Exit fullscreen
5) Scroll up and play video player
6) Click fullscreen in video player controls (left most button)

Actual Result: Video player switches to fullscreen for a second and minimizes.

Re: Fullscreen breaks YouTube fullscreen in Android Chrome [SOLVED]

Thank you for reporting this problem.
I have been able to replicate a similar problem when useFullscreenExpand="TRUE" in WebKit browsers (Chrome and Opera) on my PC and I have logged a bug report with the developers.

I notice that your gallery currently uses Juicebox-Pro v1.4.4.1.
Please try upgrading your gallery to the latest version of Juicebox-Pro (v1.5.0) to see if this helps with the problem on Android.
Full instructions for downloading the latest version can be found on the Upgrading Juicebox support page.

If the problem still occurs with the latest version, then I can add appropriate notes to the bug report.
Also, please let me know if the problem occurs in any other browsers on Android, e.g. the stock Android browser or Firefox (if you've tested in any browsers other than Chrome).
The more information we have, the better.

Setting useFullscreenExpand="FALSE" should be a suitable workaround for Chrome and Opera desktop browsers until the bug is fixed but Juicebox automatically uses the Fullscreen API on Android so, unfortunately, I do not think that there is a suitable workaround for Android.

Thank you, once again, for reporting this issue.
