Unable to show panes when all panes are hidden in DockManager #8102
Description
Bug report
In the DockManager component, the togglePane() method works correctly when at least one pane is visible, allowing the user to toggle the visibility of other panes. However, when all panes are hidden, the method fails to show any of the hidden panes when invoked. This issue prevents the user from displaying any panes once all panes have been hidden.
Reproduction of the problem
Here is an Dojo reproduction: https://dojo.telerik.com/oUPaNLbQ
Current behavior
When all panes are hidden, the method fails to show any of the hidden panes when invoked.
Expected/desired behavior
When all panes are hidden, to correctly show the hidden panes.
