Remember fullscreen state
Problem
Currently, Epiphany remembers window size but not fullscreen state. Therefore, when a fullscreen Epiphany window is restored, there is no way to make the window non-fullscreen or interact with the browser chrome, which is hidden.
Steps to reproduce
- Make Epiphany fullscreen
- Restart device
- Open Epiphany
- Observe that while the window is fullscreen, the user cannot interact with the browser chrome, which is hidden and cannot be revealed.
Proposal
Epiphany should remember fullscreen state in addition to window size, such that it knows it is in fullscreen mode when a fullscreen window is restored.
