The real problem is that frame's document is not updated by the time re-layout is triggered. Checking document for being in cache before re-layout seems to be an appropriate workaround (for me at least :) ). 

The ideal solution would be changing frame loader logic so that the view is re-created after the appropriate document had been set, but this looks like a quite significant change of the commonly used (and very complex!) code with a huge risk of various regressions.
