Mouse Buttons don't fire InputBegan event if you click left and right button at the same time

When both mouse left and right button down, One of them doesn’t fire the event.
It happens on both studio and in-games.

The script to reproduce the bug:

Output when mouse Left and Right click at the same time:

Either Left or Right mouse button doesn’t fire the InputBegan event and register as pressed.

It is affecting my games since certain mechanics require both mouse buttons down.

Can you provide a repro rbxl of this behavior? Thanks!
