Allow linking to needgap comment url from this page

I attempted to enter a link to https colon slash slash needgap dot com slash comments slash 1099 in the comment below, in an attempt to provide partial reproduction instructions, but I received an error saying that there was an invalid url

Unfortunately I also can't enter the full url into this comment either for the same reason, so I've written out "colon" and "slash" and "dot".

Is this expected?

Thanks!
