After enabling the extension R syntax on Positron, my .Rmd chunks "disappear" / are not able to run.
I have the quarto extension installed in order to run chunks in my .Rmd files (but not quarto itself installed)
With R-syntax extension enabled:

I get the error: Cannot execute code because there is no registered runtime for the 'rmd' language.
With R-syntax extension disabled:

I'm guessing R-syntax overrides the quarto chunk availability.
Ideally, I want to have the easy access to rmarkdownrender from R-syntax, and the possibility to run code chunks at the same time.
