Ability to lock crouch removed Windows 10 (disparity with mobile)

In 1.14.6 and before players could toggle crouch to stay on during normal gameplay by using the default key combination Shift + Alt. 1.16.0 this feature does not function. Was this change intentional? If so this moves the Windows 10 version out of sync with the mobile client. On all mobile devices there is a dedicated key/button to toggle crouch. Please bring the platform back in sync.
