This seems a bit odd to me, especially when, e.g., sharing a link with a long URL. More often than not you'd format the link inline to be human-readable, but the length of the URL itself is often outside the poster's control (and from what I understand, the usage of URL shortening services can be viewed as a controversial practice). Even without considering other formatting marks, from the perspective of potential URL lengths alone, you might not be able to even share a single link within a comment (600 limit vs ≤ ≈2,000), even despite the hypothetical poster's intent to perhaps only have the frontend output (±) a single word.
I'm curious if this functional limitation is intentional? Or perhaps it'd be very challenging to implement that type of evaluation on the backend? Or does the community simply not get bothered much by it?
