## Message

```
Respect max line limit for invisible character replacements (#57137)

This change makes sure that `LineWithInvisibles::from_chunks` applies
the max line length limit to invisible character replacements as it does
to normal text chunks.

Without this change, pathological lines containing many invisible
characters could produce unbounded number of line fragments.

Closes FR-6.

Release Notes:

many invisible characters.
