Unfortunately this scenario is missing from the test cases, because the extension is already started when we open its details in the "about:addons" page, and even the "addon disable/enable" test cases is not able to catch this issue because in that scenario the "optionsURL" attribute on the addon details HTML element has been already set to the real WebExtension optionsURL (which is only available once the addon has been started). Unfortunately, the entire "options box" element is hidden (from the aboutAddons.css CSS rules) when optionsURL is an empty string. A reasonable fix can be to remove the "optionsURL" attribute completely when the addon is a WebExtension (the attribute is not actually used for rendering the WebExtension options and the attribute will be added back when the user navigates on a legacy extension, which is the only scenario where that attribute is actually used).

This issue is verified as fixed on Fennec 57.0a1 (2017-09-07) under Android 6.0.1. Extension options are not hidden when about:addons is already opened and the extension is still starting. Please see the attached video.
