Textbox Overflow Handling - Scrollbar not Saved with the File

Hi

I like the new feature of the Scrollbars of Textboxes by overflow.
I have only one problem. If I select the "Add Scroll Bars" an Publish the Version has a scrollbar, but this Setting will not saved in the .story file.

On Reopen the Storyline File, it is back to "Allow text to overflow" without Scroll Bar.
