when using data-position="fixed" for our header and footer with JQM 1.1, this results in strange behavior in Opera Mobile 12 when scrolling, esp. the footer is most of the times displayed somewhere in the middle of the viewport after a scroll. This happens in the Opera Mobile 12 Emulator as well as Opera Mobile 12 on some Android Phones. This used to have some problems in pre 1.1 also (eg superfluous whitespace at the bottom of the page), but not as severe as with JQM 1.1. This is with jQ 1.7.1, if this matters.
Opera Mobile 12 seems to have problems with position: fixed.
navigator.useragent contains for the emulator "Opera Mobi/32904" while on the device I see "Opera Mobi/ADR-1203051631". Current version running on a tablet returns "Opera Tablet/ADR-1205181138". The former is greater than the number used in supportBlacklist, the latter is not expected by the coding there.
Additionally I would like to see an easy possibility just to amend supportBlacklist, Currently I have to copy and modify it.
