I'm a bit worried that the implementation of SyntheticWebTouchEvent is robust
enough to expose to developers, but that's a separate patch.

I'm not convinced it actually manages the index correctly in cases such as:
Press finger 1.
Press finger 2.
Release finger 2.
Press finger 2.
Release finger 2.
Press finger 2.
Release finger 2.

Can you take a look at how we behave in that case, and make sure it works
correctly?

It works fine, I added a test.
