bug(Listbox): Can not select first option with Enter after calling .goToFirst() (@angular/aria)

[petterhoel]

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

No response

Description

When calling .goToFirst() the first option is set active. But it is not possible to select it with Enter. If the user hits arrow down one time you can select the first option. But my whole reason for calling .goToFirst() is so the user do not need arrows when first option is the one they want.

I suspect an underlying keyboard manager is not being synced when calling `.goToFirst()'
