Bug: Button behavior (state) after click not correct

[dfsbb]

Describe the bug
When I click a button (any mode), after the click the state of the button should go back to default. At the moment after the click the button state stays on hover/focus. Only when I take the focus off the button the state changes. That's in my opinion not correct.

Affected are: public library, business library

To Reproduce
Steps to reproduce the behavior:

1. https://angular.app.sbb.ch/business/components/button
2. click on the button
3. after the click the state of the button is still hover/focus

Expected behavior
After the click the state of the button should go back to default state.

In my opinion the focused state (which this is), should also be highlighted.
@Frenggi What is your opinion on this?

[dfsbb]

@kyubisation yes you're right. Maybe I explained it not exactly. ;-) What I mean is, that after a click on a button the focus should not stay on this button. See sbb.ch behavior of the timetable search.

[kyubisation]

You could easily do this by setting the focus in the (click) event handler on the desired element, which should have the desired effect.
Or am I still misunderstanding something?
Because from an accessibility aspect it's not the best design to simply remove the focus.

[dfsbb]

Okay, I see...
So maybe we should think about to change the focus state styling?
https://digital.sbb.ch/de/webapps/components/button onClick looks like the hover state. But should the focus state really look exactly the same as the onClick and hover state? I have never seen that in forms before, that a clicked button still looks like clicked or hovered after the click. ;-)
@Frenggi, what do you think?

[Frenggi]

As already discussed bilateral with @dfsbb, I agree that the button should not look the same after a click.
When I check other design systems (e.g. material design) the "focused" and the "onclick" / "pressed" are separated visually. I think we should do this as well. And then the button stays focused after click.

@mcilurzo there's no design specification for this. Can you have a look, please?
