Mobile: map not movable with pan using Chrome Mobile

[llienher]

Using GMF 1.6.14 (so the last minor release), mobile interface doesn't work anymore with the panning.
The issue is only visible on Chrome mobile but not with other browsers.

However I saw on a project that using a commit from master, so which is more recent than the release, that it works. Our 1.6 demo is actually broken so it is not possible to test correctly.

It may be related to some changes from Chrome that doesn't behave the same with touch events.
Here is a the log that I get when trying to pan:
[Intervention] Unable to preventDefault inside passive event listener due to target being treated as passive. See https://www.chromestatus.com/features/5093566007214080
