Steps to reproduce:
- Enable Wikitext syntax highlighting
- Open your sandbox
- Edit it as source
- Type [[foo1|<span>foo2</span>]]
Expected results:
The span tags are highlighted.
Actual results:
The span tags are not highlighted, they are the same black color as the "foo2" text.
Comments:
This is probably similar to T108447 / T170240, but not exactly the same problem.
