    Description

      WiredTiger has several optimizations in place that skip comparisons where prefixes are known to match.

      There have been several bugs recently, which have manifested due to errors in deciding when those prefixes match. WT-10461 and WT-10961.

      The intent of this ticket is to add logic to the lex_compare_skip function that checks to ensure the (supposed to be common) prefixes do actually match.
