Hi! When I go to that URL (in the URL field), Safari starts using 100% CPU, beachballs, and doesn't seem to come out of it. After about fifteen minutes (!), the half-rendered page seemed to change and some of the content disappeared (as if it were in the middle of a reflow or something?) I am using WebKit Nightly build 72487. Attached are sample logs and a webarchive.
Created attachment 75215 [details] Sample log from WebKit during beachball
Created attachment 75216 [details] Webarchive of page that causes beachball
The saddest part is that result page doesn't even have De Niro's famous ad-lib. I suppose they only index the shooting scripts. The beachball reproduces in 72896.
Confirmed with r72777. Unfortunately, this doesn't happen with the web archive. *** This bug has been marked as a duplicate of bug 50221 ***
