Location: https://meta.wikimedia.org/w/index.php?title=Special:Translate&group=page-Wikivoyage%2FWhy&action=page&filter=%21translated&language=tl.
Browser: Chrome 90.

ext.translate.special.translate.js

	changeFilter: function ( filter ) {
		if ( !checkDirty() ) {
			return;
		}
		mw.translate.changeUrl( { filter: filter, showMessage: null } );
		state.messageList.changeSettings( { filter: getActualFilter( filter ) } );
	},

	changeUrl: function ( params, forceChange ) {
		var uri = new mw.Uri( window.location.href );
		uri.extend( params );
		Object.keys( params ).forEach( function ( key ) {
			if ( params[ key ] === null ) {
				delete uri.query[ key ];
			}
		} );

		if ( uri.toString() === window.location.href ) {
			return;
		}

		if ( !forceChange && history.pushState && $( '.tux-messagelist' ).length ) {
			history.pushState( uri, null, uri.toString() );

I don't think using a different way to changing the URL will avoid this error. It seems the problem is that a DOM element is making its way into the serialization here, which is not something browsers generally support. As for how, I don't know. The above code shows null being passed, so I'm not sure what is leading it to serialize a DOM element here.

Last seen on 2021-09-15. Looks good to me.
