[Bug 20311] Clarify touch-action is only looked at during pointerdown

https://www.w3.org/Bugs/Public/show_bug.cgi?id=20311

--- Comment #1 from Jacob Rossi [MSFT] <jrossi@microsoft.com> ---
I believe there’s some language missing from the spec to clear things up.
Here’s perhaps a more concise description of the behavior (emphasis on the last
sentence):

When a user touches an element, that element's -ms-touch-action property
determines the default touch behaviors permitted for that contact, like panning
or zooming. The touch behavior is then performed on the nearest ancestor
element that is capable of that behavior, unless an intermediate ancestor
element specifies that the behavior is not permitted.

Would adding that clear things up?
