Moving cursor to the edge of the wrong screen will cause flow to switch devices. Flow/screen configuration is M2 Macbook with 3 total displays, including built-in, is to the left of PC, which has its own 4th display. Macbook's built-in display is to the far left of both other monitors, with no gap or "isolated edge" for Flow to get confused on (see screenshot). However, moving cursor to exactly the right edge of the Macbook's built-in screen triggers Flow to switch. This does not happen when moving to the right edge of the center display.

Expected behavior is for only right edge of rightmost display to trigger Flow switch.
