I have observed that if a user adds a very long URL/links to their posts if gets out of the their post box which doesn't look good. In other words they are not wrapping inside the users posts.
It may have been already reported but it thought if I could share.
Verified in: Brave v1.26.67 and Chrome v91.0.4472.114
Check the below screenshot to understand it better.
It can be fixed if we could add "word-break:break-all;" CSS property to the generated anchor element either directly or by adding a class but I'm not sure of its overall impact.
