Update to knitr breaks quarto?

[giabaio]

I believe that one of the latest changes in knitr breaks quarto (see this). I think the problem is that commit #2443 has reverted the code to a small inconsistency (as discussed in #2248).

Downgrading knitr to a prior version sorts the issue, though...

I hope this is helpful?

Indeed #2243 has broken quarto, but not related to #2248 directly.

@yihui I am available to discuss this. This is the addition of a new argument in add_html_caption() that breaks quarto, because of its usage in Quarto code base too.

Either something to fix in Quarto, or we should take more into knitr how Quarto is using our internals functions in a specific way.

[yihui]

Like I said last time, we should make as less use of assignInNamespace() as possible in Quarto. Modifying a package's internal functions is bad practice in general. If that's really unavoidable, at least Quarto needs to test against the dev version of knitr so that we can discover such problems early.

We could move some R code from Quarto to knitr conditioned on is_quarto().

[yihui]

It's great that Quarto is being tested against the dev version of knitr now. I wonder if there's anything else we could do for this issue.

I think initially I left that open regarding quarto-dev/quarto-cli#5704 (comment)

We fixed in quarto for 1.3 (patch) and next 1.4 but their could have been issue with user having oldest Quarto (bundled in RStudio for example) and updating knitr.

This issue here so that we could see if something (workaround conditional to quarto version maybe ?) was needed. It seems there was no more report of this so maybe we're good.
