Unable to paste from clipboard on iOS browsers

[Chien-pinWang]

• Open ownCloud page from iOS mobile browsers like Chrome or Safari
• Click on the "+" button and create a new text file, give it a name
• An empty text file opened. Finger-tap on the blinking cursor at the first empty line but unable to get the pop-up for copy/cut/paste...
• Text can be entered by typing on keyboard though
• Tested on Chrome and Safari and both behave the same
