Steps to reproduce:

1. Go to https://developer.salesforce.com/docs/component-library/bundle/lightning-dual-listbox/example
2. Turn on NVDA
3. Focus on Available list
4. Select a value and then press space/enter on the 'Move selection to selected' field
5. Notice it doesn't work the 1st time and focus is lost
6. Activate it a 2nd time

This works as expected with JAWS or Voiceover.

Actual behavior:

When a user presses enter/space on the Move selection to selected button to move an item to the 'Selected' box, nothing happens on the first try. A user has to action the button a 2nd time to move the selected item over.
Focus is also lost after the 1st keyboard activation.
The issue doesnt happen in reverse when moving items from right to left.

Expected behavior:

After taking action on the Move button, space or enter should work the first time to move an item over. Focus should stay on the trigger element.
