Not reproducible on v1.2 (APK taken from https://github.com/mozilla-mobile/firefox-echo-show/releases/tag/v1.2)

This is interesting.

• Fresh install of release v1.3
• Open to YouTube
• Fullscreen -> toolbar will be visible (broken)
• Open menu
• Navigate to Wikipedia
• Open menu
• Navigate to YouTube
• Fullscreen -> toolbar will not be visible (working as intended)

This problem is reproducible when pushing the v1.3 APK listed under releases (https://github.com/mozilla-mobile/firefox-echo-show/releases/tag/v1.3), but is not reproducible when building v1.3 debug from source.

This is also not reproducible with a locally built, release flavor, v1.3 APK.

We are resubmitting 1.3 as 1.3.1 to see if this corrects the issue in production before devoting further time to investigation here.
