I couldn't help notice when trying to click a link in a channel that it wasn't possible if it was a certain length?
For example (using randomly chosen links):
[01:03:23] <@Jigsy>
https://bing.com/ is not clickable
[01:03:29] <@Jigsy>
http://bing.com/ is clickable
...
[01:12:09] <@Jigsy>
http://di.fm/ is not clickable
[01:12:13] <@Jigsy>
https://di.fm/ is not clickable
