Write an English word press "Home" button on your keyboard and write an Arabic word, you'll get Arabic letters splited which is not right.

And it was working fine in the older versions 

when I mean write I mean writing inside an input box (input type="text")

Reproducible: Always

Steps to Reproduce:
1. Write an English word in an input field
2. Press "Home" Button in your keyboard
3. Try typing an Arabic word and you'll get splited letters not a whole word
Actual Results:  
broken Arabic words

Expected Results:  
Normal Arabic words just like when typing after using English word
