This resolves https://github.com/owncast/owncast/issues/3240
From the comments:
This was trickier than expected, but the root of the problem is Firefox will set `#` in the URL bar when `window.location.hash` is set to _any_ string, even a blank string. The morale of the story is, don't mutate base data if you just want to copy values. 😅
Sample of Firefox JavaScript console session that demonstrates the issue:
```javascript
>> window.location.href
"https://github.com/owncast/owncast/issues/3240"
>> const setBlankHash = () => { window.location.hash = ''; };
undefined
>> window.location.hash
""
>> window.location.href
"https://github.com/owncast/owncast/issues/3240"
>> setBlankHash()
undefined
>> // My browser just jumped to the top of the page
undefined
>> window.location.hash
""
>> window.location.href
"https://github.com/owncast/owncast/issues/3240#"
```
