3663844 - SAC : Unexpected results when using API .length property of Input Controls in Story

• When using .length property API in scripts to determine the number of elements in an array when selecting members within an input control, it returns unexpected results.
• Since the last patch week (21-22 June 2025), it was observed a change where the length calculation directly returns 1 for "A1," bypassing the hierarchy levels. This alteration has disrupted several functionalities, as it would rely on the length value to simulate single selection input controls with hierarchies. Specifically, a length of 3 indicated that only a single country was selected.
• Historically, the length calculation included each level of a hierarchy. For instance, selecting "A1" in a hierarchy structured as Root → A → A1 would yield a length of 3, accounting for all hierarchy levels.
• We expect that the ancestors of selected members being returned by the API

This isn't an expected behavior - parents/ancestors node of selected members shouldn't be returned by this API.

• It works as Designed
• Parents/ancestors node of selected members shouldn't be returned by this API, except all the children under parent/ancestors have been selected.
