1. Illustrator CC 22.0.0 on Windows 10 x64 Pro

2. Have a column of Area Text, justified, with carefully defined line breaks so that words are hyphenated at particular places, or not hypenated at all.

3. When using either the scale tool (shift+click to scale proportionally) or the transform tool, all of the content should scale proportionally and the line breaks should not be changed.

4. The resulting rescaled text column has very slight changes to the line breaks. While shift+dragging, the text looks correct (just scaled proportionally, without any reflow or stretching), but when releasing the mouse, there is suddenly some text reflow on some of the lines. This destroys some very carefully set line breaks. What I want to happen is to make the text column larger with the line breaks exactly the same. This is not an issue of just scaling the text box, the text itself is also changing size - but not accurately. Checking/unchecking the "scale strokes and effects" in the transform dialog doesn't have any effect. The most frustrating thing is that once I have scaled to a new size (with the broken flow), scaling seems to work just fine - I can use the scale tool to proportionally scale the text with the "wrong" line breaks. It doesn't come up with new text flow each time.

I suspect that Illustrator is mishandling or ignoring font tracking or kerning values when scaling.
