Trailing space in links in metadata block

[martinthomson]

Description of problem

Example here: https://w3ctag.github.io/privacy-principles/

In the metadata header of this document, I see HTML like the following generated for all parenthesized lists:

<a>linked text </a>( <a>link </a>, <a>linked text </a>)

Observe how there is a trailing space on each link. This should instead be:

<a>linked text</a> (<a>link</a>, <a>linked text</a>)

Or maybe there should be a single space inside the parentheses, that's a valid stylistic choice, I guess.
