Hi Iulia,
I don't really get why this blocks the PE Windows meta bug 1315189 as the bug was reported when PE is OFF.

Hello! 
The main idea of this issue was that the maps.google.com functionality shouldn't be affected by PE status, meaning that the site should be fully functional (like www.bing.com/maps does), no matter if PE is preffed on or off.

Thanks Iulia!

Hi Stone, I am wondering how this issue is impacted by PE. Ideas?

Can't reproduce it with nightly 55.0a1 (2017-05-17) (64-bit) on Windows 10 (with dom.w3c_pointer_events.enabled=false). Single click on a store, UA shows store information on the left side of the map. Double clicks can zoom the map. Wondering is there anything I missed

Oh, I guess the problem only happened with touch.

Yes, according to the test report, this is an issue with touch.

It looks like single tap works fine (UA shows the store information on the left side of the map when single tab on some store). Double tap can't zoom in as our expectation.

Also found that the double tap didn't work on Edge and Canary when pointer event disabled.

Does that mean it's google maps issue?

Hi guys,
Is this Google's issue after all? We are having a pre-Beta sign-off this week and I wanted to know if this is an effect of Pointer Events and if we should keep it in our radar or it's just a Google issue and we should ignore it for now. 
From comment #7 it seems that it's Google's problem :)

Very sorry for replying late. According to the testing results, I think it's Google's problem but I didn't dig deeper to double confirm it. I'd do more analysis when available (probably one or two weeks after).

Verified with nightly build 59.0a1 (2018-01-04), single tap works fine and double tap still doesn't work. Edge also behaves the same. Can't test it with Chrome because now I can't find the flag to turn pointer event off. I think this is the problem of content. Feel free to re-open it if any concerns. Thanks.
