Created attachment 111733 [details] Screenshot demonstrating the bug The plaintext message viewer makes URLs it recognises clickable. However, this only works for short URLs, up to 255 characters. At 256 characters and above, URLs are no longer clickable. This is a problem, since such long URLs are fairly common. For example, when Kickstarter and Patreon send project updates through e-mail, the links include long random tokens, almost always pushing them over the 255-character limit. Attached is a screenshot demonstrating this effect, with a text/plain e-mail with two URLs, one of 255 characters and one of 256.
