Movement error after typing

In first or third person, all movement work like normal (using bluetooth keyboard and mouse)

WASD work like it should, but after typing when searching for an item, inserting a command using / or placing a name on a sign, then WASD does not respond normal. Also the movement buttons onscreen do no longer work like they should.

To replicate the problem, start a game...walk around... then place a sign with text, or type a command.. After that, try to walk again.. So will see that it will not work like normal. Previous versions of Minecraft like the 1.15 dit not had this problem.

I am using Dex on a Samsung Galaxy S20 Ultra with a bluetooth keyboard and mouse.
