But that's an absolute URL, provided a well-defined base URI exists (the
authority is implied and the path component starts with a slash, so it
would start in the root).

Then Safari either has a bug or it determines the base URI differently
than Chrome.

I don't think so.  You might want to read

https://tools.ietf.org/html/rfc3986

specifically the part about the translation of relative URI.

Thanks for the pointer. 

It helps because it states that:

"Some parsers allow the scheme name to be present in a relative

   reference if it is the same as the base URI scheme.  This is

   considered to be a loophole in prior specifications of partial URI

   [RFC1630].  Its use should be avoided but is allowed for backward

   compatibility."

And on page 21:

"If the URI scheme defines a default for host, then that default

   applies when the host subcomponent is undefined or when the

   registered name is empty (zero length).  For example, the "file" URI

   scheme is defined so that no authority, an empty host, and

   "localhost" all mean the end-user's machine, whereas the "http"

   scheme considers a missing authority or empty host invalid."

So exporting to <a href="" is wrong.

I guess I can solve that with a filter.
