In Illustrator scripting, the constant Justification.FULLJUSTIFYLASTLINELEFT does not work as expected.
It behaves the same as FULLJUSTIFY, with no option to align the last line left (or center, or right).

InDesign scripting supports full justify with last line alignment correctly, which makes it possible to automate proper typesetting.
Illustrator should support the same behavior, so scripts can handle justified text layouts consistently.

This limitation makes it impossible to automate professional typography workflows in Illustrator.
Please fix this or implement the same functionality as in InDesign.

Thank you.
