This signals to me that your new action does not begin with a / or a http(s)://.

This is normal browser behavior.

If you assign a fully-qualified URL or a complete (root-relative) path to either an a#href or form#action, the browser will accept that. But if your new URL or path is not complete, then the browser will attempt to "canonicalize" it by adding the current context to it.
