This is similar to bug 396645 and is what's causing stress-11.xhtml in the first-line reftests to fail. When we insert the caption, the first-line frame ends up as its parent, and since that's an inline as far as we're concerned we make the anonymous table an inline table.
This got fixed in bug 148810. stress-11.xhtml has been passing since.
