Step 1: Write a long string of text inside a text box. (Anything works, but written books will work the best)

Step 2: Try to change the cursor's position by clicking on the text.

Expected result: The cursor's position will change to where you clicked, allowing you to edit the text.

Observed result: Nothing will happen, and you will be forced to use the keyboard's arrow keys to navigate the menu. This is very annoying when playing on mobile devices, as there is no way to change the cursor's position at all. In order to edit text that you have typed previously on mobile devices, you need to delete all of the text in front of it. 

Please fix this as it makes writing in command blocks and written books very difficult.
