Hey,
I've noticed that if I have a line of text and I try to delete the newline at the start of the text, instead of moving the text up to the previous line, it will instead delete a character from the line above. This seems to be specific to track changes and can be replicated on your track changes demo. The steps to reproduce are as follows:
1. Type a few words
2. Hit the enter key
3. Type a few more words
4. Click at the start of these words and press backspace
Observe that the new line generated by the enter key is not deleted, but the character previous to that one. This behavior is different in the track-changes demo than in the regular telerik editor demo.
I look forward to hearing back from you, and I hope that this is an easy fix.
Kind regards,
Aidan Harris
