[useCombobox] InputKeyDownEnter action not triggering when focus is on the input field on version 6.1.0

[lasota-piotr]

• downshift version: 6.1.0

• node version: 14.2.0

• yarn version: 1.22.10

Relevant code or config

function stateReducer(state, actionAndChanges) {
    const { type, changes } = actionAndChanges;
    // Doesn't log when a user has focused on the input and pressed enter
    console.log(actionAndChanges);
    return changes;
  }

What you did:

1. I clicked on the input and typed hi
2. I pressed enter

What happened:
It didn't log actionAndChanges variable

Problem description:
The problem is the same as here #1114 but on version 6.1.0. On version 6.0.4 works correctly.

Should the state of the component change once you pass enter? If not, then stateReducer should not get called. Before #1218 it was broken, that's why you got that called.

If you need to execute your own logic independent from downshift then use your own event handlers.
