Multiline Text fields no longer support word wrapping in 2021 R2

In 2020 R2 and all prior versions, the user could see the full text of the note, e.g. Problem Details on a Case entry, while entering the text.  In 2021 R2, the text entered scrolls off the entry area in a single line.  This is not helpful and appears to be a bug.  Is there a workaround?
