Microsoft’s office URI schemes conflict with the list separator of allowed\_href\_schemes.

I can’t allow scheme like `ms-excel:ofv|u|https` for the full link `ms-excel:ofv|u|https://contoso/Q4/budget.xls`
Having an escape character or quoting the scheme string would be great.

This is not a web compatible scheme, it refers to different concepts.

I checked out the code and it turns out that the separator is chosen intentionally because all the schemes are stuffed in a regex and the regex is used to match links.
In the settings I used `ms-excel:.+` to bypass the filter and now my links work as expected.
Turns out it’s not a bug, it’s a feature! 😆
