[Bug] [Splitscreen] Unable to use 3 controllers for splitscreen

Current Behaviour

Setup

• Using alpha 2 of the splitscreen mod from Patreon with Modrinth App
• 3 Xbox Wireless Controllers
• Minecraft is maximized, not in fullscreen mode

If I connect 2 controllers and start splitscreen mode, everything works fine.

But after connecting 3rd controller, pressing start, splitscreen mode initializes again and it displays message in the 3rd player's screen:

This Minecraft window is currently being hidden as splitscreen is in fullscreen mode and this is not the host client. If you see this, please report it as a bug.

Not exactly sure what does the error message mean, as fullscreen mode is not being used.

Expected Behaviour

I'm able to use 3 controllers to play in splitscreen mode, without error messages.
