Currently, when clicking in a link in the article tab, it replaces the article itself with the new page.
And when clicking in a link in a comment, it opens in the external browser.
These links should be opened on the in-app browser, instead.
Ideally this should be configurable. (In this case, with in-app browser disabled, it should open article links in the external browser IMHO, and not replace the article with it).
