I have a webmap in which I've formatted the HTML pop-up as two tables. In the webmap the pop-up looks fine and everything aligns left. EVERYTHING in this pop-up is formatted as a table - even the top half that doesn't show cell boundaries.

When I use this map within Dashboard, the very same pop-up behaves as right-aligned:

My pop-up HTML is attached. I've shoved a bunch of left-align statements everywhere to try to force the behavior - to no avail.
Any thoughts on what is happening here?
