Steps to reproduce

Create app with PopumMenuButton
Set icon using icon property e.g. icon: Icon(Icons.more_horiz
Set color using color property e.g. color: Colors.white

Expected results

Documentation for the color property:

If provided, the background color used for the menu.

If this property is null, then [PopupMenuThemeData.color] is used.
If [PopupMenuThemeData.color] is also null, then Theme.of(context).cardColor is used.

Expect that the color of the popup card change

Actual results

The color of the icon changes.

Code sample

PopupMenuButton(
  icon: Icon(Icons.more_horiz),
  color: Colors.white,
  itemBuilder: (context) => [...]
)
