Capitals in Figure label strings break rendering

Bug description

When labeling figures, capitals in the label string cause the entire label to be unrecognized. "WARNING: Unable to resolve crossref @fig-data-weeeWho" Nothing in the documentation for references makes this appear to be expected behavior. This also impacts the numbering and captions. This behavior is appearing in Visual Studio Code 1.75.1 run on a MacBook Pro M1 Pro running Mac OS 13.1.

May be related to #1186. Sorry, not sure how to shrink the sample to <20 lines.
