Splitscreen - crosshair flickers/disappears when other players open a UI

Steps to Reproduce:

1. Open up Minecraft on a split-screen-compatible device (Xbox, Playstation, Switch, etc. No servers)
2. With a second controller, add a second player to start split-screen
3. Have either player open up their inventory or any other menu (Any UI)

Observed Results:

Any players that don't have any menus opened up will see that their crosshair is flickering. When all players in a menu exit the menu, all players' crosshairs will return to normal.

If 2 players are in a menu, the other players' crosshairs will disappear but if a 3rd person enters a menu, the player not in a menu will have a crosshair and it will be flashing more intensely.

Here is a video that demonstrates all variations of flashing and no crosshair:

Expected Results:

The crosshair should stay solid and not flicker nor disappear when players open up a menu.

Notes: 

Players going into 3rd person also trigger the flashing and/or crosshair disappearing.
