Implicit Grant Flow doesn't redirect with respect to the #hash in the redirect url

[seweso]

I set and use the callback url "https://local.test:5500/#/callback", which works in the sense that the url is accepted as valid. But the #/callback part is stripped off and spotify redirects to "https://local.test:5500/#access_token=..." instead. 

I can (and will) work around that, but its rather peculiar. It could have been   https://local.test:5500/#/callback#access_token=...

I tried adding an extra # at the end, but everything behind the first # gets removed. And also weird, the part after the hash is stripped but it does need to be correctly passed as the redirect url. 

If you are thinking that I must be doing weird stuff, then you are correct. Lets just say the hash determines whether spotify support even needs to be enabled, and I just don't want spotify specific code to run when I don't need spotify. 

I want the url to be something like:

callback in settings: https://local.test:5500/#callback

redirect-uri: https://local.test:5500/#callback#anything

used uri: https://local.test:5500/#callback#access_token=...#anything
