[Button] [Popover] Pressing the Enter/Space key on "kendo-button" does not show anchored Popover element

[georgi-sla]

Describe the bug Currently, when there is an attached Popover to the element and the user navigates to the button and presses the Enter/Space key, the button is 'clicked' but the Popover is not getting rendered.

To Reproduce

1. Create a Button component.
2. Anchor a Popover to the Button.
3. Navigate to the Button using the Tab key.
4. Press either Space or Enter when the Button is focused.

For further reference, please check out the following StackBlitz demo: https://stackblitz.com/edit/angular-p8jn9p

Expected behavior Pressing the Enter/Space key when the Button is focused should 'click' the Button and should render the Popover element.

Additional context The issue is not present when using the native HTML button element and the kendoButton directive.
