bug#29047: 26.0.90; shr hang (regression from 25.3)

[Mike Kupfer]

Displaying the attached email with MH-E (using "emacs -Q") or Gnus leads
to a hang in shr (CPU is pegged, I waited for 5 minutes before giving
up).  The HTML looks pretty gnarly, but Emacs 25.3 displays the message
just fine, with maybe a pause of a couple seconds.

In GNU Emacs 26.0.90 (build 2, x86_64-pc-linux-gnu, X toolkit, Xaw scroll bars)
