embed src causes internal traversal to extend to foreign domain

[Munter]

This code causes hyperlink to recursively traverse http://www.cc.com despite being called with the -i flag that should ensure that only site internal pages are traversed:

<embed src='http://www.thedailyshow.com/sitewide/video_player/view/default/swf.jhtml'></embed>

Output:

$ hyperlink -ri BUG.html
Guessing --root from input files: file:///Users/pbm/
TAP version 13
# Crawling internal assets
ok 1 load BUG.html
ok 2 load http://www.thedailyshow.com/sitewide/video_player/view/default/swf.jhtml
ok 3 load http://www.cc.com/shows/the-daily-show-with-trevor-noahsitewide/video_player/view/default/swf.jhtml
ok 4 load http://www.cc.com/shows
ok 5 load http://www.cc.com/shows/hart-of-the-city
ok 6 load http://www.cc.com/shows/crank-yankers
^C

Looks like a redirect chain from this embed src ends up on a html page, which hyperlink doesn't correctly identify as cross domain.

Maybe HtmlEmbed needs to be handled the same way as anchors and iframes here?

hyperlink/lib/index.js

Line 638 in d07ea7c

['HtmlAnchor', 'SvgAnchor', 'HtmlIFrame'].includes(relation.type)

Fixed in 5.0.4
