Moving text with a non-breaking space [ ]

Hi,

I've noticed a strange behavior. If you select a text including a non-breaking space (wherein the code   is replaced by a "yellow space") with the mouse and move it to a different position, the non-breaking space is converted into a normal space.

The behavior does not occur when copy and paste is used or the passage contains the code   instead of the yellow space.
