[Mamoru1234]

Actual behavior:
According to this line onTouchStart is required property.
Expected behavior:
onTouchStart should be optional.

@Mamoru1234 dang, good catch. Yep, onTouchStart needs to be onTouchStart? I'll get a fix in this evening please just no-op it for now if you can get by

@scniro thanks for attention. It's critically simple to fix exactly this case, and I have created PR with fix.
But general problem why npm run test passed when code in tests are not valid example?

@Mamoru1234 I don't enforce any of the type checking for the tests. I probably should after seeing this (lol). PR merged, will bump a publish in a few moment

@Mamoru1234 fixed with the 5.0.1 release
