[evgenitsn]

PPDSC-2215

What

1. Background - Users should be able to use ref
2. What did you do - Added forward ref too

• AudioPlayerPlaybackSpeedControl
• banner
• banner internal
• base floating element
• label
• modal
• ordered-list
• popover
• standfirst
• tabs
• tag
• title-bar
• tooltip
• unordered-list

I have done:

• Written unit tests against changes
• Written functional tests against the component and/or NewsKit site
• Updated relevant documentation

I have tested manually:

• The feature's functionality is working as expected on Chrome, Firefox, Safari and Edge
• The screen reader reads and flows through the elements as expected.
• There are no new errors in the browser console coming from this PR.
• When visual test is not added, it renders correctly on different browsers and mobile viewports (Safari, Firefox, small mobile viewport, tablet)
• The Playground feature is working as expected
