Exiting nested fullscreen results in whole app un-fullscreened
Steps to reproduce
- Enter fullscreen mode in Epiphany (hamburger menu -> fullscreen)
- View content that can be fullscreened (like a video, e.g. https://ftp.osuosl.org/pub/fosdem/2023/Janson/matrix20.mp4)
- Enter fullscreen for that content
- Exit fullscreen for that content
- Observe that the fullscreen mode in Epiphany is not preserved, i.e. the Epiphany window goes un-fullscreened
Proposal
Do not make Epiphany exit fullscreen mode when exiting nested fullscreen content
