When going through notifications and attempting to follow links to web pages, the overwhelming majority do not work. This is frequently the case when dealing with markdown links, which can be followed readily on the web.
Addtionally, most of the content cannot be highlighted or selected, which makes me believe this regression is due to some press/click handler being overly greedy.
Attached a screenshot of a sample message with a link suffering from this issue.
