Crash while scrolling feed

Some observations:

• It only happens when .lineLimit() is attached, which we only do when viewing a feed with 'large' posts. Therefore it's a problem with the rendering, not with the parsing logic.
• It happens in both SwiftMarkdownUI and LemmyMarkdownUI (when using MarkdownText).
• The crash occurs most of the time, but not always.
• The text contains non-ascii ♪ characters, but removing them doesn't fix the issue.
• A similar-length string of a single repeated character does not cause a crash.

I can't repro this anymore. Assuming this is fixed
