App crashes when the mouse is over a message while scrolling

[kovapatrik]

The app crashed while I was scrolling through a room. It seems to happen when the pointer ends up to the right of the text in messages that have several paragraphs. I built the app locally, and the exception was:

#1	0x000000010e958884 in MessageTextContent.linkRange(at:) at Relay/Relay/Views/Message/MessageTextView.swift:445

Did you submit a crash report when this happened? That shares the full stack trace with me.

I just sent a report tagging this issue. Although I'm not 100% sure this is the same issue I just explained, but the app crashed again while I was scrolling in the app. I cannot reproduce the crash if I scroll by grabbing the scrollbar, I only get this if I scroll with the mouse's scroller while hovering some messages (especially long messages).

There have been other reports of long messages causing some ScrollView jumping too.
