render --to pdf and ::: {.content-visible when-profile="MYPROFILE"}: why is preceding empty line required

[r-cheologist]

Consider a *.qml file like this:

Profile-dependent content follows:

::: {.content-visible when-profile="MYPROFILE"}
Content requiring `--profile MYPROFILE` to be added to a `render` call
::::

This works just fine, but when omitting the empty line preceding ::: {.content-visible, the container is not recognized and printed verbatim.

Is that by design or a bug?

[cscheid]

That's by design. What are you trying to accomplish? If you're looking for an in-paragraph version of content-visible, that's currently not supported: only entire blocks can be hidden or visible at once.
