http://demo.goseamless.co.za/cktest/ - this link contains an example of code with the bug
try typing in the editor on an iOS device, then move the cursor around by
tapping in a different place in the editor. and carry on typing, the
editor stops responding, then closing the keyboard and tapping again to
edit allows you to type.
Also the Next/Previous buttons on the iOS on screen key board ignore the
editor when "tabbing" through controls
