Quote blocks disallows interior ">" paragraphs

Currently if a block contains a quote paragraph indicator > , a deprecation warning appears and the quoted text is hidden.

If a block is already a Quote block, it still happens – the Quote block hides the >-quoted paragraph. My use case is quoting something that’s quoting something else.

I would like to be able to show quotes using the > syntax inside Quote blocks.

(I’m guessing this is a bug; if not please consider it a feature request.)
