Describe the problem in detail

The comment is not properly highlighted.

Describe the behavior you expected

Correct highliting of R comment.

Also if your comment ends with |, it breaks syntax highlighting of roxygen comments

I would expect a regular R comment ending with | to not break syntax highlighting in R files (I suspect it may be due to enhancement of highlighting in Quarto files, which is awesome.

I just noticed this while working on gt, since they have a logo on top of each file

• I have read the guide for submitting good bug reports.
• I have installed the latest version of RStudio, and confirmed that the issue still persists.
• If I am reporting an RStudio crash, I have included a diagnostics report.
• I have done my best to include a minimal, self-contained set of instructions for consistently reproducing the issue.

Reproducible. Note that the problems occurred in different releases:

• The incorrect comment formatting appears in 2023.12.
• The incorrect roxygen formatting appears in 2024.04.

This occurs in R Markdown and Quarto chunks, as well.
