P: Free transform introduces unwanted warp
Photoshop 21.0.3 on Mac OS 10.15.3
Under certain free transform conditions a Warp is introduced without user input.
1) the original free transform 
2) when the lowermost point is moved further down the upper left side gets unwarrantedly warped
3) this warp is also visible when switching to warp
The file is available for testing here:

If anyone takes the time please let me know if you get similar unintended results.
