            Bug ID: 183667
           Summary: Safari load event stalls
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: iPhone / iPad
                OS: iOS 11
            Status: NEW
          Severity: Major
          Priority: P2
         Component: Page Loading
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: shimon.schwartz at cbsinteractive.com

Summary:
When you load www.cbsnews.com on Safari on iOS 11.3 beta 1-5, the load event often hangs. 

Steps to Reproduce:
1. Open Safari
2. load www.cbsnews.com or any internal page on the site

Please note we've noticed that it could be related to Akamai mPulse (SOASTA) product, which is used to measure performance on a lot of sites on the web. When we disabled the Boomerang tag, the hang was gone, however once we re-enabled it, the progress bar started hanging again.

Also, please note this does not occur on iOS 11.2 or lower, nor on any other devices.

Expected Results:
Progress bar finishes within 2-10 seconds

Actual Results:
Progress bar hangs in the middle for a long time, sometimes never finishes.

Version/Build:
iOS 11.3 betas 1 through 5

Configuration:
Standard iOS beta version
