Description Luke Warlow 2021-09-08 09:59:23 PDT

Steps to reproduce the problem:
1. Navigate to https://jsfiddle.net/40abpv7d/
2. Look at the HTML output


I'm not entirely sure on the correct behaviour. Chrome, Firefox and Safari all behave differently.

Chrome - https://%22google.com/
Safari - https://"google.com/
Firefox - TypeError: URL constructor: https://"google.com is not a valid URL.


As I say I'm not sure if Chrome, Firefox or Safari is "correct" as far as the spec is concerned. But from what I as a web developer expect I would say that Firefox is the most correct, followed by Chrome. Safari's behaviour of outputting a non URL safe string surprises me.

According to https://url.spec.whatwg.org/#forbidden-host-code-point WebKit is correct here.  I look forward to other browsers either changing to match the spec or raising an issue with the spec for discussion.  It seems like Firefox intends to match the spec here.
