ScrollBar not showing when content size changed?

[siba_tatsuya]

Creator Version: 3.4.2

1. Create a new ScrollView with a Vertical Scrollbar.
2. Set the content to be smaller than the view:
   2.1. Content have Layout component with ResizeMode is CONTAINTER
   2.2. Item of content have Label component with Overflow is RESIZE_HEIGHT
   2.3. Make sure content have height smaller than the view
3. Set up a button, when click button, it will change label with a long string and make sure content height larger than view height.

At init time, scroll bar hidden, and when I click button to change label, scroll bar still hidden. Please check!
