Filing this as a followup to bug 1900278 / bug 1850834 for a specific case that's still more expensive that bug 1900278's mochitest exercises.

tl;dr: if a <table> element is empty, then setting its textContent to the empty string seems to be more-expensive (in terms of frames reconstructed) if the table is part of an IB split, even after the patches from bug 1850834.

This isn't an issue anymore; I think one of emilio's updates to his patch stack may have fixed this. I was able to my test-patch in bug 1900278 to remove the failure allowance for this.
