Cannot enter ephy-reader: addresses in address bar
I cannot enter ephy-reader: addresses in the address bar. Epiphany just does a DuckDuckGo search instead. I tried modifying ephy_embed_utils_address_has_web_scheme(), and you already updated EPHY_WEB_VIEW_NON_SEARCH_REGEX, but it seems something else is needed.
P.S. Ideally we would not have to update two (and more?) separate places when adding new URI schemes.
