In Reader Mode, tapping the address bar should expose the actual moz-extension URL

[opusforlife2]

Currently, the address bar shows the original page's URL even if you tap on it. There is no way to view or fetch the Reader Mode URL from there. There is a workaround: bookmark the page, edit the bookmark, view/copy the URL from there. Quite tedious.

If the user wants to share a Reader Mode URL with someone for whatever reason (like the page is full of ads and other irrelevant stuff), they should be able to do that without using the workaround I mentioned above.

• The menu options like Share can continue working with the original URL.
• But simply by tapping the address bar and copying the moz-extension URL from there, a user should be able to copy/share the Reader Mode URL.

(I think desktop Firefox should also show the full about:reader URL in the address bar, if the domain name at the top is changed to show the full URL of the original page instead.)

In Reader Mode, tapping the address bar should expose the actual moz-extension URL.

moz-extension:// URLs are not shareable and only stable per device. So, the current behaviour is intentional. When sharing via the share menu, we already use the original URL instead. The moz-extension URL will not work for anyone else you share it with.

We have mozilla-mobile/android-components#2879 on file to use a custom protocol similar to about:reader.

Is there any issue tracking this functionality in this repo, though? If not, shouldn't there be one?
