im using a pre3 with webos 2.2.4 but maybe it is a problem on the other devices too.
anyway, when using the browser and you tab on a textinput field the browser zooms in on that. Especially on mobile pages that are made for the screen size i find this really annoying cause its just not needed imo and i always have to zoom out to see the whole page again.

Maybe this is fixable with a patch. That would be awesome
