+++ This bug was initially created as a clone of Bug #149968 +++ When a page has an unscalable viewport (for instance, user-scalable = no or minimum-scale = 1, maximum-scale = 1) we should not have to wait 350 ms for the double tap gesture recognizer to fire.

Can you upload a test case showing the problem?
This is resolved now that https://bugs.webkit.org/show_bug.cgi?id=149968 actually landed in 9.3 beta - see http://patrickhlauke.github.io/touch/tests/results/#suppressing-300ms-delay
Sounds good.
