quarto-1.4.80-macos unable to recognize the content of the "block" in div when compiling beamer.

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?

Checklist

• Please include a minimal, fully reproducible example in a single .qmd file? Please provide the whole file rather than the snippet you believe is causing the issue.
• Please format your issue so it is easier for us to read the bug report.
• Please document the RStudio IDE version you're running (if applicable), by providing the value displayed in the "About RStudio" main menu dialog?
• Please provide the output of quarto check so we know which version of quarto and its dependencies you're running.
• Please document the operating system you're running. If on Linux, please provide the specific distribution.

Start by reproducing the supplied .qmd block example with quarto-1.4.80-macos while compiling a beamer document, then compare the generated output with the previous version described in the report. Done means the {.block} div is rendered as a beamer block rather than leaving only its content; the issue does not name a source file or test to inspect.
