Cushions should take exactly 4 seconds to break without support. (Reliably)

Replacing the supporting block of a cushion with a different one has already become a common and versatile building technique. However, currently it requires fast mouse movement to avoid the cushion "popping off" while its supporting block is temporarily removed. The time it takes for a cushion to break due to the lack of a supporting block is currently also slightly randomized.

I would like to suggest changing the time cushions take to break due to a lack of support to exactly 4 seconds, and also removing the randomization from it.
This would make it easier to swap out their supporting block without having to worry about them breaking.
