Data Fetching bug on the "Manage Items" Screen

There is an issue with the data fetching behavior on "Manage Items" screen.
To request a fix, I will create a Question in CCC.

Navigation Path:

Product Management > Product Information Management > (task)Manage Items > (search particular item) > (tab) Structures > (select one)

Reproduction Procedure:

Expand the bottom child item ⇒ Select the bottom row ⇒ Expand another item ⇒ You can't make the bottom row show by scrolling!

*It seems that data fetching does not occur when only one row is not displayed on this screen.

I've created a screen capture video of this bug. Please refer to it
