DropDownList in Toolbar's oveflow is not clickable

[martintabakov]

Bug report

When there's a DropDownList in the Toolbar's oveflow, clicking to open the DropDownList closes the overflow popup.

Regression introduced with 2023.1.117

Note: As of 2023.1.117, the DropDownList is no longer overflowing, despite overflow: "always". As of 2023.1.425 the DropDownList is again displayed in the overflow, and can no longer be opened.

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/mJFCLzOS/8
2. Click on the overflow menu, and try to open the DropDownList

Current behavior

The overflow popup closes

Expected/desired behavior

The overflow popup should remain open so that you can interact with the DropDownList
