Incorrect line weight scaling after vertical reflect command
With "Scale Strokes & Effects" turned on in preferences, using the transform panel to change the length of a line after it has had the vertical reflect command used on it will incorrectly scale the line weight.
Attached images show the scaling behaviour after the vertical reflect command has been performed.
Adobe Illustrator 2023 27.8.1 64-bit
Process Architecture: x86_64
I have the same behavior. Illustrator 27.8.1
Can confirm it
