Unsolved Strange cursor behavior when editing QML in text editor

[Ilya Lazarev]

Hello.

Very annoying behavior - cursor jumps to first char on line when I start typing property value and have not completed yet.
For example:

1. I type 'title:'
2. type 'qsT'
3. Wait about a second.
   *4. Cursor jumps to home position.

This behavior have being observed up to the latest qt creator version as well.

Please give me some clue..
Regards.
