Korean Input Bug - Deleting Korean characters also removes characters in front of the cursor.

Hello.

I think I found a bug. I'm running the most recent version of Animate on OSX.9

When I am entering Korean letters (hangul) into Animate, and try to delete them, letters in front of the cursor also disappear.

This only happens if I try to delete a letter in a syllable that is currently being edited. Finished syllables don't have this problem. For example, if I want to type 한 but I type 해 by mistake and try to delete the ㅐ, the phenomenon occurs.

Thanks for the great program though!
