Ensure syntax highlighting is the same inside diffs (#12205)

Browse source 
Make sure to end up with the same syntax highlighting inside various sections of diffs by processing the code first before detecting specific changes between the lines. Also try and make sure that when highlighting individual lines in a diff that it is tokenized the same as it would be when part of an entire file with more context.

Fixes: #12190
