Example URL showing sarken's works filtered to only those including the "Graphic Depictions Of Violence" warning:
Sometimes, folks bookmark search or filter results in their browser. If the thing they are bookmarking includes warnings, that will no longer work as expected after – basically, it will fail silently and include works regardless of warning.
We'd like to make sure URLs like this that use the warning_ids parameter name keep working.
How to test:
Filter a tag by a particular warning - say, Main Character Death. Make note of how many results you get.
Copy the url to a text editor and find-and-replace “archive_warning_ids” with “warning_ids”.
Paste the new url into your browser bar and see if you get the same results.
