WIP CL for Mac support is at https://crrev.com/2622733002.  Unfortunately, as-is it seems that mouse events injected by the test are received by product code with weird cordinates (after the drag starts).

Are you filing this bug to track your work in the CL above, or because you'd like to hand it off?

I am not actively working on this right now - please feel free to take ownership of the bug and the CL.

Thank you very much!

I'm a bit swamped at the moment, so all I can do is make sure that the bug is triaged correctly. Thank you for helping out with that!
