1497557 - <a> "protocol" shows as "http:" for data-relative paths, instead of ":"

Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, enhancement, P2)

Description

[Logan Smyth [:loganfsmyth]]

If you load a data: URL on Firefox with a link on it, the `protocol` of the <a> is supposed to be ":" (because it's an unparseable URL), but Firefox appears to returning "http:" or "https:" for the protocol.

For example, if you load this and look at the console:

    data:text/html,<script>console.log(document.createElement('a').protocol); </script>

this will log "http:".

I think the source of the "http" result is here

Thank for the pointer. I think it's an easy enough fix.
