@hashar and I were able to fix most of the MultimediaViewer browser tests Jenkins jobs.

browsertests-MultimediaViewer-en.wikipedia.beta.wmflabs.org-windows_7-internet_explorer-8-sauce is still broken. mmv.performance.feature fails with JavaScript ​error and Watir::Wait::TimeoutError .

I will submit a patch that disables scenarios that fail. If you do not care about those scenarios running in IE8, no action is needed. If you care about the scenarios and need help fixing them, let me know. I do not have the time to fix them myself, but I will be glad to pair with somebody from the team on fixing them.
