I discovered that there is no test coverage for the OnClickData properties for the "audio" and "video" context types in the contextMenus / menus API. The full list of context types is at: https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/menus/ContextType The following two files provide some test coverage for most of the types, except "audio" and "video": https://searchfox.org/mozilla-central/rev/d29c832536839b60a9ee5b512eeb934274b879b0/browser/components/extensions/test/browser/browser_ext_contextMenus.js page link selection image editable password https://searchfox.org/mozilla-central/rev/d29c832536839b60a9ee5b512eeb934274b879b0/browser/components/extensions/test/browser/browser_ext_menus.js page_action browser_action tab page frame tools_menu

see also bug 1398453

Note: The added test may increase the odds of triggering the timeout threshold, bug 1469836. I'll monitor that other bug to see if additional action is necessary.
