Hi @inuyaksa

Thanks for submitting a pull request.. Note that this broke a lot of tests, and I'm not sure which of the changes is the one responsible.

Can I ask you two things:

1. Create two pull requests. Each one should handle either Pinch zoom broken in Chrome v55.02883.91 on Mobile #303 or Unable to preventDefault inside passive event listener due to target being treated as passive.  #328.
2. Make sure that the tests pass, or fix the tests, justifying why the current tests are wrong.

Thanks!
