Confirmed on Xbox One S in 1.16.0.61 Beta

@Kyle Alexander Goempel you mean confirmed fixed, or confirmed to still be occurring in 1.16.0.61?

It seems to affects everything that you can do by holding jump. So if you open a UI while climbing up a scaffolding you will still climb and if you open a UI while swimming up in water you will still swim up.
Resolving issues that were marked as fixed in the 1.15 and 1.16 Betas, now that 1.16.0 is being released.
Seems to be fixed in 1.15.0.51 beta, can anyone else confirm?
