I experience the exact same behavior (infinite loop) many times each and every day. Today, I installed the first RC, Version 0.99.136.1-rc (WebKit 623.1.8.0.0), and the problem remains. It is rarely the immediate page I get to after a web search but seemingly always after I select a button on that website to go so a secondary site.
Here is a URL from RottenTomatoes that exhibits this behavior:
https://editorial.rottentomatoes.com/article/one-battle-after-another-first-reviews/
As the OP observes, the same URL that evokes this behavior in Orion RC loads and behaves as expected, renders a page without repeatedly reloading, in Safari.
Searching for a workaround just now blew away a tab group (yikes), but I also discovered that by disabling Javascript for a site that exhibits the behavior, i can get the reloading to stop.
Maybe there's a common JS library that is a trigger?
