ui5-combobox focus method not working

[ee92]

Describe the bug
Using the .focus() method of the ui5-combobox does not work as expected. After calling .focus(), the ui5-combobox does not become the document.activeElement, does not have the focus outline, and has the .focused property set to false.

To reproduce
Steps to reproduce the behavior:

1. Go to https://sap.github.io/ui5-webcomponents/playground/components/ComboBox/
2. Using the dev tools, save a ui5-combobox as a variable
3. Call .focus() on it and notice it does not get focused as expected.

Expected behavior
When .focus() is called on the ui5-combobox, it should become the document.activeElement, should have a focus outline, and should have the property .focused set to true.

Hello coleagues,

There is a missing data-sap-focus-ref attribute and therefore the component is not focused.

@ee92 , as for the outline - it is not rendered as the focus is in the console while executing the .focus() line.
It should work fine in the app logic.

Thanks,
Tereza
