The user tour functionality includes a feature to highlight a specific element in the UI. When a specific feature is highlighted in this way, then the tabindex is set to include the element in the tab index.

When we introduced enhanced control of ARIA attributes in MDL-68390 this broke this feature as only the currently active element and it's parent tree should be focusable.

We need to determine:

• if it is correct to unhide the element in question;
• if so, how we do so; and
• if not if there's something else that we should be doing instead.
