Bug 107607 – [Chromium, Mobile] Do not show disambiguation pop up in mobile sites

• Component: WebKit Misc.
• Status: RESOLVED FIXED

Corresponding Chromium bug:
http://crbug.com/168117

For mobile sites, it seems unnecessary to make a disambiguation popup since the page should be designed specifically for ease of use on a mobile device, e.g. touch targets should be big enough to click on without ambiguity.

Do we have other heuristics like this elsewhere?  Should we use the same one consistently?  If not, should we factor this code in a way that future code that wants a "is mobile site" heuristic can use it too?

Also, we need a test.

I think I found the code you mentioned for the 300ms simulated click event delay Chromium-side, in ContentViewGestureHandler.java.  It seems pretty specific, though: because our double tap action is to zoom in, we simply don't enforce the trigger the delay when there is a fixed page scale.

I'll dig around some more for other current possible use-cases, but I think factoring out the code is a good idea, regardless.
