Closing & reopening the webrtc connection loses the mouse & keyboard inputs

[skornous]

Description

Since the rework of v4 a bug was present where if you closed & reopened the WebRTC WebSocket you'd lose the inputs from both mouse & keyboard.

After some tests it appears that unregistering the mouse & keyboard events in the store on WebSocket disconnection & then re-registering them when creating the peer connection (as for the touch & gamepad events) fixes this issue.

This PR is the aforementioned fix.

Sorry but as it's quite a technical issue, it's hard to provide a simple screen-record so you'll have to trust me on this 😬
