[PATCH 0/1] MR5954: dinput: Call handle_foreground_lost() synchronously in cbt_hook_proc().

[Shaun Ren (＠shaunren)]

mouse_unacquire() needs to be called on the same thread as
mouse_acquire(), otherwise the cursor hidden by mouse_unacquire() will
not be restored.

Fixes an issue with [the cursor disappearing in the game IL-2: Cliffs of Dover Blitz Edition](https://github.com/ValveSoftware/Proton/issues/5007#issuecomment-2148093822).

[PATCH 1/1] dinput: Call handle_foreground_lost() synchronously in cbt_hook_proc().

[Shaun Ren]

From: Shaun Ren

mouse_unacquire() needs to be called on the same thread as
mouse_acquire(), otherwise the cursor hidden by mouse_unacquire() will
not be restored.
