Zoom plugin was scanning for initially disabled zoom with an improper regex that didn't catch every case. This patches the regex string, which will now catch more cases where zoom should be set to to initiallydisabled.
See later comments of issue #4024 where white screen flashes during transitions; this is what fixed it for me.
Improved regex string for matching initially disabled zoom
test initially disabled zoom though maximum scale value with decimal,…
… ie maximum-scale=1.0
Perhaps you should consider adding support for user-scalable=0 also.
@nickwb you're right, according to http://dev.w3.org/csswg/css-device-adapt/#meta-properties, acceptable values are yes, ≤-1, ≥1 or no, and between 1 and -1
fixed up more regex to be more to spec; see http://dev.w3.org/csswg/css-device-adapt/#meta-properties
which says user-scalable can be yes, no, or a number, where anything between 1 and -1 is interpreted as no. Also switched to non-capturing groups
