Issue with R Markdown syntax highlighting

[iago-pssjd]

Hi!

I have an R markdown file for which syntix highlighting produced by 'R Markdown.sublime-syntax' goes well until it does not, inside a for loop. I paste below a screenshot fragment where you can see when highlighting becomes odd:

I believe the issue happens when the parser detects the three backticks starting a chunk, but which are inside single quotes in knit_child.
