It only affects code fence in markdown. The colorization works fine in .cs files

See screen shot

The token says it is an operator, but somehow the bracket pair colorization still treats it as brackets.

Research direction
Investigate why the bracket pair colorization treats `>` as a bracket in C# markdown code fences but not in .cs files. Look at the tokenization logic for markdown textmate grammar and the bracket pair colorization extension. The file likely resides in `src/vs/editor/contrib/bracketPairColorizer/` or similar. The fix might involve updating the bracket pair definitions or the tokenizer to exclude operators from bracket matching.
