### Bug description

A very frustrating problem, which did not exist in my previous version.

I want to input the Block block in beamer as follows in QMD:

:: {.block}
content
:::

So that it can be displayed as a block in be after compilation. This was successfully done in previous versions, but cannot be achieved in the latest(quarto-1.4.80-macos). After compilation, only content is displayed instead of the block.

Has this feature been removed from new version or is it just a bug?
