        <pre>Some Amazon ads cause WebKit to hang with 99% cpu usage - as shown by "top" command for WebKitProces.

Fedora Linux:
epiphany-runtime-3.26.6-1.fc27.x86_64
webkitgtk4-2.18.6-1.fc27.x86_64
RedHat Linux Bugzilla 1551610 - epiphany (WebKit) hangs with 99% cpu for certain web pages

Bug is very reproducible.

Steps to reproduce:
1) Turn off ad blocking in epiphany browser
2) Go to URL <a href="https://www.amazon.com/Dragons-Egg-Dragon-Eggs-Book-ebook/dp/B01JOL7BKC/ref=sr_1_1?s=digital-text&ie=UTF8&qid=1520258748&sr=1-1&keywords=dragon%27s+egg+Sorensen">https://www.amazon.com/Dragons-Egg-Dragon-Eggs-Book-ebook/dp/B01JOL7BKC/ref=sr_1_1?s=digital-text&ie=UTF8&qid=1520258748&sr=1-1&keywords=dragon%27s+egg+Sorensen</a>

This URL is not unique - it is the ads which are causing the hang - viewing other Kindle books (and probably other items) will also cause a hang (sometimes).  Not all ads may cause a hang.</pre>
