Copy paste bug

**OS **Windows 10

Katalon Studio Version 5.3.1 Build 1

Copying from a test case, which got collapsable items, is producing duplicate items.

Example:
Testcase A, contains: Openbrowser item; for loop statement (expanded) which contains Authenticate item

Copying with CTRL+A,CTRL+C, then pasting the items into Testcase B will result in the following:
Testcase B, contains: Openbrowser item; for loop statement (expanded) which contains Authenticate item; Authenticate item after the for loop

If you copy while everything is collapsed then there wont be duplicate items.
