If an URL is cropped on a line wrap, only the first line will be clickable and considered as an URL.
We could trim the URL and use a term API to make them go to the right resource, however it is not implemented by tcell:

Another solution could be to implement a shortcut (like alt-l in weechat) that shows the timeline fullscreen, in log format, to allow the terminal to correctly see the URLs.
In the mean time, either use a URL shortener, or trim the URLs (eg. query parameters are often useless).
emersion has a patch for tcell to support hyperlinks: https://github.com/gdamore/tcell/pull/468
If someone wants to implement this, I've made a tag on my tcell fork with emersion's patch:
