Jira Cloud header dropdowns don't work on some pages

Question

I just converted our old JIRA on premise installation to the cloud.  It appears that the dropdowns along the top bar (Dashboards, Projects, Issues, Boards) will break on some pages.  I've so far discovered that I can duplicate the error when going to the "Gearbox" -> System page.

I'm in Chrome, and there is a warning that I see on all the pages:

Dropdown constructor has been deprecated and will be removed in a future release. Use Dropdown2 instead.

I can work around this issue by navigating to other pages, but it's kind of annoying.  Has anybody else seen this?  Any idea about when this will get fixed?
