Browser freezing due to NoScript XSS protection

I can reproduce 100% on https://www.tripadvisor.com/Tourism-g60763-New_York_City_New_York-Vacations.html, on Linux 64 (Ubuntu 18.04). Before page being completely loaded, the whole browser freezes for a while (at least 60 seconds), then some XSS popups appear.

Unticking NoScript Preferences -> Advanced -> Sanitize cross-site suspicious requests fixes it, so I assume this is being caused by NoScript XSS protection. I was surprised that the whole browser is freezing, but it must be that the NoScript WebExtension runs in the main process.
