Issue

By mistake when typing more than one superior diacritic on one base character you cannot see that this has been done. It should follow the behavior of inferior diacritics. When you type by mistake more than one inferior diacritic on one base character the second etc. diacritic will not combine with the base character.

1. Open a Word document

2. Load the Windows Burmese keyboard

3. Type "u"+"d+d+d". You cannot see that you typed three superior diacritics because they are on top of each other like in this screenshot.
   

4. It should look like ကိိိ
