QML autocomplete corrupts code

When writing QML code in the editor, when selecting autocomplete option (I use up/down arrows, then enter), sometimes it corrupts the code by placing the autocomplete text and deleting about 15 characters before and about 15 characters after. It takes 2 undos to get back to my partially completed line of code.

It seems to only happen on autocomplete to the right of a colon, in the binding statement, but this might be luck. i.e. if I'm typing `anchors.margins: myConstants.myMarginConstant` then I've not seen it have a problem with selecting `anchors` or `margins` but I see it with selecting `myMarginConstant`.
