The timeline extension generates a <map> tag which gets typeof and about attributes added to it by the ExtensionHandler. But, the sanitizer strips these attibutes from the map tag since it is not whitelisted. We need a fix to the sanitizer: either whitelisting of additional tags for approved extensions, or blanket whitelisting of extension-output-marked tags.
We should be able to blanket-whitelist mw: typeofs if we strip those from user content early in the token stream. This is covered by bug 48772.
