fix(session): track mouse movement activity

[Antreesy]

☑️ Resolves

• Fix Move mouse or scroll chat but without focusing on window still marks session inactive #11126
  • document => document.body fixes behavior on Firefox with event registration
  • mouseenter now mark session as active, mouseleave restarts a timer
    • moving the mouse and scrolling within tab borders should be covered, as mouse entered the tab by that moment

🖌️ UI Checklist

🚧 Tasks

• To test:
  • Set INACTIVE_TIME_MS to a lesser value (or wait 3 minutes)
  • Unfocus window (switch to another, or start screenshare)
  • Enter mouse cursor onto tab and leave like this
  • Wait for interval - session should be still active
  • Move cursor away from tab
  • Wait for interval - session should be marked as inactive

🏁 Checklist

• 🌏 Tested with Chrome, Firefox and Safari or should not be risky to browser differences

@SystemKeeper for checking on Safari

Not working in safari it seems:

maybe try mouseover and mouseout ?

[SystemKeeper]

I tried to add (also tried mouseover):

		document.addEventListener('mousemove', (event) => {
			console.log('Move')
		})

But I only see "Move" output when the window is focussed in safari, as soon as another window is focussed, no 'Move' is logged.

Scrolling seems to work:

		document.getElementsByClassName('scroller').forEach((element) => {
			element.addEventListener('scroll', (event) => {
				console.log('Scroll')
			})
		})

but not sure if this also fires when we programmatically scroll.

Tested as well, seems that MacOS tries to save resources here, on inactive tabs:

• For Safari events on blurred window are disabled
• For Chrome they work, but throttled (caught 1 mousemove event compared to hundreds on active)

So I'd raise an issue to track that for Safari cases, but see nothing we could do atm

[DorraJaouad]

As discussed, it is fine to skip Safari for now.
Tested on Firefox and Chrome ✅
