Works very well for me. dieulot, is there a small bug with the allowQueryString check? const allowQueryString = 'instantAllowQueryString' in document.body.dataset I think should be: const allowQueryString = 'instantallowquerystring' in document.body.dataset If I have: <body data-instantAllowQueryString="foo"> then 'instantAllowQueryString' in document.body.dataset === false and 'instantallowquerystring' in document.body.dataset === true because html data attributes get converted to lowercase by the browser (I think).
