Tab icon is not displayed

I’m using various interface elements to learn HR. When an icon is set to a tab it does not show up. Is it what is expected?
Thank you

Tab icons only work when the TabBarPlacement is set to Bottom. Icons are not supported in tab bars at the Top.

There is also a refresh issue with those icons in the Designer. After you set the icons for each tab, close the page & reopen it. Then you’ll see them.

Thanks Bill this is clear
