6.2.12 MOBILE Can't copy permalink

OS/Browser/device: iOS 5, 6, 7 / Safari / iphone 4S and Android 4.2.2 / Chrome / Nexus 7
Use case: open application, zoom somewhere, go to the "Share" section, try to Copy + Paste the permalink out of the textbox
Result: The link can not be copied
Expected: the link text can be marked and copied

I'm not sure, if this is an app issue. Could be an issue of iOS?
