Looks like this was fixed by bug #127701. In the future, WebThreadRun() is IOS only, but callOnMainThread() will cause the passed function to be called on the web-thread (regardless of it's name).

Should upload a new patch. EWS was unable to apply this one.

Can’t we go straight to the web thread? Why do we need both?

Indeed, and that's what we did in bug #127701.  Marking this bug as a dup of that one.
