Hello !
Sorry to have miss your first post.
This is indeed a change in rmarkdown following a change in htmltools on how raw HTML content is preserved.
Are you using these function in a blogdown project ? Or in another type of project ?
BTW you should try the dev version of blogdown that should handle this correctly. If not, we'll need to fix.
As a workaround you can deactivate this by using dev version of rmarkdown and setting the option options(htmltools.preserve.raw = FALSE)
However, I would like to know when this is happening. With which format ? in which type of project ?
For xaringan, you should try last dev version which should handle this well.
Can you share more on the examples ?
Thank you !
