When opening an IconButton Tooltip on mobile (tested iPhone with iOS 14), it will show the Tooltip, but also show the "copy, define, share..." callout menu and selects some elements.

It should only show the tooltip.

EDIT: I know this happens basically for all buttons. But for normal buttons there's no reason to long press them, though it's not a real issue there.
