Topics for PE WG call

I wanted to suggest the following topics for our next PE WG call.

- Follow up on the last week issues

   - Should "click", "dblclick" and "contextmenu" events be PointerEvents?
   <https://github.com/w3c/pointerevents/issues/100> (Update from Bo)
   - Extend pointer events to support raw trackpad data
   <https://github.com/w3c/pointerevents/issues/206> (Update from Bo)

- And the following issues:

   - Too many other behaviors interrupt pointer events (dragstart,
   touch-action) <https://github.com/w3c/pointerevents/issues/213>
   - Mouse back/forward buttons: page navigation or JS events?
   <https://github.com/w3c/pointerevents/issues/191>
   - How to determine when a tap is impossible
   <https://github.com/w3c/pointerevents/issues/124>

Cheers,
Navid
