Go to this page in e10s mode: http://slightlyoff.github.io/ServiceWorker/spec/service_worker/#service-worker-global-scope-script-cache Perform a full refresh (shift-ctrl-r). I am consistently placed at "3.2.6 Event handlers" instead of the correct "4.1.1 scriptCache". Not sure this is the correct product/category...

works for me

Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:46.0) Gecko/20100101 Firefox/46.0 Build ID: 20160204004009 The issue is still reproducible for me on the latest Aurora 46.0a2 on Windows 10, Mac OS X 10.10 and Ubuntu 15.04. Reproduced the issue by using the following steps: 1. Navigate to: http://slightlyoff.github.io/ServiceWorker/spec/service_worker/ 2. Scroll down and in the Table of Contents click on "4.1 ServiceWorkerGlobalScope" 3. Refresh by hitting the keys: Ctrl+Shift+R. Expected results: The page is refreshed and I should be placed at "4.1 ServiceWorkerGlobalScope". http://slightlyoff.github.io/ServiceWorker/spec/service_worker/#service-worker-global-scope Actual results: The page is refreshed but I'm placed at "3.4 ServiceWorkerContainer" This is reproducible regardless if e10s is enabled or disabled. Setting the status of this report to REOPENED.

not e10s specific.

Since originally reporting this bug I've realized that the service worker spec is dynamically changing its style/layout. I believe its this dynamic change which causes the scroll position to be off. I suspect they are using some kind of web components polyfil.

Mass bug change to replace various 'parity' whiteboard flags with the new canonical keywords. (See bug 1443764 comment 13.)
