User control of zoomlevel in Hybrid

There was a request for user control of the zoomlevel (ctrl-+, ctrl--) in a Hybrid application.
Right now the situation is:
It seems to work for a split second, then the Hybrid picks up a resize event en ignores the user zoom.

There are two reasons for not implementing this:
- This behaviour is consistent with the goal of the Hybrid: Making a consistent user-experience, no matter what browser or previous settings as much as is technically possible.

-We might make it default behaviour and have the programmer override it at will..
However:

The following discussion reveals a rather pained process of dealing with all the browser-quirks involved. Without extensive browser sniffing this does not seem possible to do  yet in all browsers,

Browser sniffing or UA sniffing is generally considered bad practice because of reduced scalability, increased maintenance and the existence and common practice of 'browser masquerading' and is therefore against the Hybrid design policy.
