I use a subscription service (www.expertflyer.com), and recently with nightly build #44552 a page that previously rendered correctly in nightly build #44524 no longer renders. I can see the data is in the page by examining the page's source code, but it is not being rendered.
Created attachment 31482 [details]
Added html page that should be able to repro the issue without subscribing to the service.
This happens because we now have an incomplete implementation of JSON object, which confuses the web site.
Fixed now that 26587 is completed.
Please verify in current nightly :D
Verified the table is now correctly rendering in build r44932.
