Bug report

When a Kendo UI ExpansionPanel is nested within another, and the initial expanded configuration is set to false, the panel will not open the first time it is attempted. When the widget is initialized, it searches for all expand icons in the expander's wrapping element, which in this case would include the icons of the inner expanders. Thus, when a user clicks on an outer one, you also affect the inner ones.

Reproduction of the problem

  1. Go to this Progress Kendo UI Dojo.
  2. Expand the main panel.
  3. Expand a child panel.

Current behavior

The Kendo UI ExpansionPanels do not open the first time clicked.

Expected/desired behavior

The inner expansionPanels should open as expected.

Can be reproduced in the official demo: https://demos.telerik.com/kendo-ui/expansionpanel/api

1. Click on "Expand"

2. Try to Collapse by clicking on the Panel

-> Panel does not collapse, but gives a short animation and expands again.
