Target window (new con) woes

[ReilenBlaeyze]

I'm trying to modify the new con style target window to display health and power percentages.

Now as we know there is some dead space in the window, so I put the text labels just below the ornate border.

This is working just fine when I target a monster, but when I target an PC or NPC the game resizes the window so my % values fall just below the window.

I've attached screenshots and XML for my target window.

Now what I need is a way to prevent the game from resizing the window, so my % labels don't get hidden.
