Errors in redisplay in eww

[Eli Zaretskii]

When browsing this page:

  https://news.ycombinator.com/reply?id=10801669&goto=item?id=10801368

I see a lot of error messages in *Messages*:

  Invalid face reference: nil [329 times]
  Invalid face reference: nil [2000 times]

Also, Firefox displays that page with indentation, so that each
response is slightly indented relative to the message to which it
responds, but eww shows everything flat.  Is that a feature?

Thanks.
