Is there any way to pass a URL parameter in Gitlab Pages?

I want to serve a static page with a URL parameter: When I load the page in Gitlab pages, I see a 302 redirect to – i.e., the params are stripped. The issue appears to be captured here, but there are no workarounds suggested.

Anyone have any suggestions on some way I can pass a URL parameter to a page? Is there a way to circumvent this behavior?
