Hiding then showing the status bar can move the insertion cursor off the bottom of the displayed document.
To reproduce: Scroll to the end of a document, put the insertion cursor at the of a document. Hide Status Bar Show Status bar
I guess it depends on where you want the status bar to 'steal its display space. I would think you would want to avoid moving the document which you currently do. That means 'stealing' from the top of the display (suggested new behavior and the inverse of of what Hide Status Bar does)). However, if the cursor is in the region to be stolen, you should probably push it down (current behavior).
