Short description of error
[Please fill out a short description of the error here]
The UV Sculpt in UV Editing doesn't work. It gets overwritten by the new tool shelf select system. And you select vertices instead of doing sculpting. Pinch Relax and Grab does nothing.
Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]
In Blender 2.79 when i unwrap a mesh and activate UV Sculpt, then i can immediately sculpt at the UV Mesh.
In Blender 2.80 when i unwrap a mesh and activate UV Sculpt, then i am trapped in selecting vertices. I can't get UV Sculpt to work. The select tools in the tool shelf overwrites the sculpt mode.
What is curious is that when you load a scene saved with Blender 2.79, then the UV sculpting works. As long as you don't touch the select tools in the tool shelf. Then it turns disfunctional, and you are trapped in selecting again.
Also, the Pinch, Relax and Grab tools seems to do nothing. Not with UV Sculpt not without UV Sculpt. Not with the whole UV Mesh selected, not with nothing selected. And the sync mode doesn't change things neither. Not sure if this problem is connected. Maybe i also overlook something here. But i report it as one bug for now since those tools are sculpting tools. Feel free to separate the problem.
And i get some errors in the console. The Pie menu related messages doesn't belong to this report. But the Unsupported Mode: EDIT error looks strange.
