Adding RB label as this is a recent regression.

Looks like this is probably a device mode regression.

Able to reproduce the issue on mac 10.11 chrome version 52.0.2723.0

This is definitely https://codereview.chromium.org/1776843003. Not sure that's a bug though - maps surely don't expect touch to appear and then disappear and could break in unpredictable ways. Over to Dave to assess whether the problem exists.

Touch Action could cause wheel gestures to be filtered.

If the source device is not touchscreen the touch action filter
should not do anything. A certain drop list in
Google maps was failing to scroll via wheel scrolling because it had
installed a touch action none filter.

Tested this issue on Windows 7, Ubuntu 14.04 and Mac OS 10.11.4 using chrome latest canary M52-52.0.2737.0 and observed the issue is not reproducible. Now it's able to scroll the apps section of google maps on closing dev tools window as expected. Hence adding TE-Verified label.
