Describe the bug
When the RadzenDropDown control is wrapped within a <label> element, clicking on the expand arrow does not do anything. If the dropdown is not expanded, clicking it will expand the dropdown for a few milliseconds before it closes again. If the dropdown is already expanded, clicking the expand arrow will not close the dropdown.

To Reproduce
Steps to reproduce the behavior:

Create a <RadzenDropDown /> control.
Wrap it in a <label> ... </label> element.
When running the application, click on the little expand arrow on the drop down; it will not work as expected.

Expected behavior
Interacting with the dropdown should work the same as when it is not wrapped in a <label> element; The expand arrow should expand the dropdown as usual.

Sample Code

<label>

	<RadzenDropDown TValue="string" Data="@values" />
</label>

	public IEnumerable<string> values = new List<string>()
	{
		"These", "are", "some", "values"
	};
}
