Commit 1146ea4 breaks appleTV menu button detection in FNA and possibly other polling-based clients

When this commit is applied: https://github.com/libsdl-org/SDL/commit/1146ea484a5972947528d5ae9b20ee874e71408d

Detection of the appleTV remote's menu button press becomes very flakey in FNA-XNA (which is a polling-based client).

Without this commit, it works fine.

EDIT: Tested on device using tvOS 26.6, for reference.
