            Bug ID: 193766
           Summary: Some websites cause busy loop making epiphany
                    unresponsive
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: benjamin at sipsolutions.net

If I browse to https://www.titanic-magazin.de, then a short time after the page is loaded my epiphany tab freezes and the corresponding WebKitWebProcess spins the CPU at ~100%.

Steps to reproduce:
 * Visit https://www.titanic-magazin.de
 * Wait until the page is fully loaded

Result:
 * Tab freezes, CPU spins

Expected result:
 * Tab remains responsive

This is happening with the following package versions:
 * webkit2gtk3-2.22.5-1.fc29.x86_64
 * epiphany-runtime-1:3.30.2-1.fc29.x86_64

I believe that this issue has existed for a long time, and I think I first saw it happening just after the website was redesigned.
