List of steps to reproduce (step by step, including full links if applicable):

• Search for something on Commons
• See that the results page shows source code all over the filtering criteria dropdown menus

What happens?:
Pretty sure the source code should not be appearing. Example: <p>All licenses</p> <!--DiscussionTools addDiscussionTools called-->
Menu options still function though.

What should have happened instead?:
there should menus (drop down, I think), instead I see html around the menu options.

Software version (if not a Wikimedia wiki), browser information, screenshots, other information, etc: Chrome v 92.0.4515.159
