Unwanted behaviour in Text layers

[RrnR]

I have noticed an annoying behavior with text layers.  I have a project with several text layers.  Now and again, when I try to move the vertical origin of the text in a layer by picking up the size bar at the top, all of my text resets to a very small size when I release the sizing bar.  I have to then manually restore the text size it to the size it was (undo doesn't seem to work).  Other formatting such as bold or font color is retained.  I can't reproduce the issue at will, but wonder if it is related to text layers overlapping one another.
