While using wacom tablet to do Liquify transformations, sometimes Transformation tool is switched to another (maybe randomly choosen) tool, and applying changes without press "apply button".
In this case there may be another unexpected behaviour. Sometimes Transform mask loose part of changes, made in previous transformations. But undo can bring it back.


Reproducible: Always

Steps to Reproduce:
I cannot describe steps to reproduce precisely, but if you have wacom tablet, you can just apply Liquify Transformations to transform mask with wacom tablet, and using mouse to change tool parameters. And after some trying you will see behaviour I describe.

Actual Results:  
Transformation tool sometimes unexpectedly switching to another tool

Expected Results:  
Transformation tool must switch only while manually switched.

I use image ~4000x3000px (8bit sRGB).
