eventPhase property of onClickCapture events has wrong value

[timjacobi]

Do you want to request a feature or report a bug?
I assume this is a bug.
What is the current behavior?
When I register an onClickCapture event handler, click on the element and then inspect the event the eventPhase property is set to 3 which is equivalent to Event.BUBBLING_PHASE.

I'm currently rewriting the ReactTreeTraversal tests to use the public API, that's how I found the problem.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.

On codesandbox I would expect an alert false and then true but it is the other way round.

What is the expected behavior?
The eventPhase property should be set to Event.CAPTURING_PHASE / 1.
Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?
I haven't tried this in versions different from 16.1.1, all testing was done in Chrome 62.

This is a known issue, see #9783. I've got an open PR that fixes this at #10722 that I just need to polish up.

Thanks and sorry for the dupe. I did some searching but didn’t find the old issue.
