Azure B2C: Allow whitespace in custom user attributes
It looks like whitespace should be allowed in custom user attributes. For example, the list of pre-defined attributes includes field names like "Given Name" and "Job Title." Since those fields seem to allow whitespace in names, I would think we can have whitespace in our custom attributes. I haven't gone far enough yet with the sample to see how these are presented to the user; but if whitespace isn't allowed and something like "ShoeSize" results in "ShoeSize" in the UI, then that's not going to be acceptable.

This can be achieved by editing the "LABEL" value associated with the attribute on the Page UI Customisation blade in the Portal. By default it is set to the same as the attribute "ShoeSize" but can be modified to read "Shoe Size". You can also re-order fields and change input type on this blade.
