Prepare somewhat of a workaround for awkward paragraph re-composition when the paragraph's container is smaller than a single glyph but those glyphs allow for line breaks, which is the normal case, e.g., in Japanese fonts. (Note that the Western default is break-on-space.)
When does this happen? Think of an empty text morph where you start typing something. But instead of typing, you paste something from the clipboard. This is where it breaks, e.g., for Japanese fonts.
What happens in that case is that the paragraph composition "explodes" downward until the maximum height is reached. The user will notice an input lag.
I will try to hunt down the actual issue but for now it makes sense to communicate the min-width from the TextMorph to the paragraph.
