Controller that demonstrates the issue, by toggling the boolean "breakWithExtraLength"

When using long strings (greater than roughly 10000 characters), that contain line breaks, URLs and email addresses beyond roughly 10000 characters are not detected and highlighted, as they are supposed to be.

I've attached a sample controller that adds a textview and demonstrates the issue, by toggling the boolean "breakWithExtraLength".

I've also been able to recreate it, with the following:

string textViewString = "";
for(var i = 0; i < 500; i++){
     textViewString += "Test addresses test@example.com http://www.example.com \n";
textView.Text = textViewString;

I have checked this issue on below environments:

XS 4.2.3 (Build 60)

I followed below steps:

1. Created iOS application.
2. Implemented attached code in created application.
3. Debug and noticed that all text is not displayed on simulator.
4. Also I check with the code as mentioned with bug description and noticed that only 15 loop text is displayed on simulator.

I can reproduce with iOS 7.1 (iPad Air), but not iOS 6.1 (iPad 3).

I can also reproduce with an equivalent Xcode project, which means that this is not a problem with Xamarin.iOS, it's a problem with iOS.
