Formatted Text Deletion Bug for iOS

When deleting formatted characters, 3 characters are deleted at a time rather than one. So, for example, if one was to type "dog" in blue and backspace once, then one would lose all three letters, whereas one should only lose "g."

I am assuming the game is trying to delete the section symbol, number/letter used to determine effect, and the visible letter, whereas it should only try to do this when at the beginning of the colored text.

This appears to only affect iOS devices
