The new permanent weakness to elements morph is, in fact, permanent. I got it applied to me, went to look at new champion points in a keep, used transitus to go back to the alliance base, and it didn't go away til I wayshrined out of the zone.
This is a major defect, and I'm a bit cheesed as I posted 3 threads about this issue, and have been going on about it in game since I first read the patch notes.
Please fix. I'm going to go get new gear because this completely changes gameplay, until it is fixed. Unless this is intended behavior, which is pretty nutty. Being marked in/out of combat in cyrodiil is a longstanding and very widely known bug.
