To help gather data on real Web content that might be helpful to the Fission teams, jwatt has a Web crawler.

Code: https://github.com/jwatt/iframe-crawler
Sample results: https://jwatt.org/iframe-crawler/display-crawl-results.html

Ideas and requests

Outstanding

Do a crawl with Fission turned off, and a crawl with it turned on, taking screenshots of OOP-iframes to be compared to look for Fission rendering bugs.
What is the max depth of cross-origin subdocs (the amount of nested processes we'd need basically)?
How often are cross-origin iframes under 'transforms' or 'filters'?

Answered

Percentage of pages with visible cross-origin subdocs? Around 25% based on initial crawl.
Frequency of 'display: none' and/or zero sized iframes.
