@Jdlrobson, I can't seem to figure out why this is happening. Do you know why?

@bmansurov luckily I have ios simulator and just connected it up to Safari and remote debugged using developer tools. Luckily this one was a logical fix :) Not sure why it doesn't show up on Chrome - is something messed up with our position fixed support?

I'm not sure either, but your fix seems to work for overlays.

@Jhernandez, it may be a good idea to look into why this is happening only on iOS. Having said that, the problem is fixed, so we may delay doing so until later.

I actually think ios is doing the right thing here and my bug fix makes sense.
The header of the search is position-fixed so with the drawer open it was correctly being transformed in ios.
I think the bug is thus in in any browser that is not doing this correctly.
https://code.google.com/p/chromium/issues/detail?id=20574 < might be the cause?

Either way I'm confident we are not going to have this issue again, so it's probably not worth any extra investment in time.

lol. awesome.

I'd really love to freely express myself by embedding arbitrary images, but that's not worthy it seems.
