Textarea iOS - autocomplete suggestion fails to be clicked

Very strange (iphone/iPad/iOS) behaviour.
When using the (Stupid) Autocomplete function on an iPhone / iPad, the dictionaty gives you some suggestions.
This 'blue' suggestions has a small 'ignore' (delete) button in the top right corner.

Strangely: tapping / clicking the autosuggestion fails in a <textarea></textarea>
But it does work in a <input type="text"">

The autocompete="off" also won't help me.
