[NW2 issue] : Setting two binded windows to a fullscreen state doesn't work anymore

[DimPaDev]

NWJS Version : 0.44.0
Operating System : Linux (Fedora 31, both kde and gnome), Windows 10

Expected behavior

When you bind two windows both in size and position you should be able also to set these two windows to a fullscreen state just like in nw1 mode (--disable-features=nw2).

Actual behavior

In Nw2 mode trying to set two binded windows to a fullscreen state results in a weird flickering issue which prevents the application to work normally.

As it is a blocking issue I will reference this to #7230

This is fixed in git and will be available in the next nightly build.

Note that restore need to be handled as well. It should be fired when exiting fullscreen, not resized event. That's an issue in nw1 mode.
