Flagging this as an important regression.
I'm going to try to fix this soon.

This happens in both the current RDM (Responsive Design Mode), and the new one (the one being developed bow behind flag devtools.responsive.html.enabled). This is most probably an issue with doing swapFrameLoader, which I think both RDM implementations do.

Only the new RDM uses frame loader / docshell swapping.  The old RDM UI has elements surrounding the xul:browser that are hidden during regular browsing and then shown when opened, so nothing is swapped with the old RDM.
