"Clear my choice" a href calls for a page reload

Unfortunately, since a last minute modification, "Clear my choice" has an odd behaviour.
Since it was conceived to simply undo a option choice, it has not been reloading the whole page. But now it is exactly what is happening, and therefore some browser prompt the "Are you sure you want to leave this page" dialogue.

Note you don't see this happening in a single question preview but you have to test this in the quiz attempt itself.
