It would be great that if using a drop-down menu to select a tab on a form experience can be improved.

Suppose there are multiple tabs (Such as Summary, Product Line items and Quotes) on a form.

When you select the tab from the drop-down menu right next to the record name and move to the selected tab, the label of the top tab will disappear.

In this case, the "Summary" tab will not be shown once a user is navigated to "Quotes" tab on a form, and back to the top by using scroll bar.

The legacy form rendering can apply a quick fix to this issue but this feature will be deprecated soon.
