If a block references another block, when copied it will not preserve the block content, but it will link to the original block.

I have uploaded two images: one in the app, other with content pasted in a github comment.

I tried to export the full page as markdown, but the problem remains. Only PDF seems to solve it, but it really doesn't because it loses the block hierarchy when copied.

Seems similar to https://capacities.io/feedback/p/block-reference-on-same-page, but what I want here is to fully copy the content without any link to the app itself.
