It seems that the most recent version of Google Chrome on Windows (v51) prevents the edit interface of EPiServer from loading, failing with the error
Uncaught ReferenceError: normal is not defined
I've experienced this issue on both version 8 and 9 of the CMS.
I've tried it out in Chrome Canary v53 and it seems to work fine, so it looks like whatever has changed may have been fixed/reverted.
Has anyone else experience this issue? Is this something EPiServer can work around or will we have to wait for the next version of Chrome to be released?
