data-toggle-is-active does not update aria-hidden attribute

1. Have exact markup like in Collapsible panel with ARIA.
2. Add data-toggle-is-active to button.
3. Reload page and note panel is expanded (working, is-active class added to button, panels aria-hidden set to false)
4. Change attribute from data-toggle-target-parent to data-toggle-target
5. Reload page and note panel is NOT expanded (does not work, is-active class added to button, but panels aria-hidden IS NOT set to true (value not changed))

Expected behavior
aria-hidden value changed to true
