Action Group Menu sometimes release too quickly and executes not clicked command

The Action Group menu sometimes reacts too quickly and treats a long press on the button (still during selection command Action from Menu) as a click and then results in the execution of the command located directly under the mouse marker.

The problem occurs when the Group Action drop-down menu is longer than the monitor height and occurs after selecting from the Menu Actions and the pull-down menu overlaps the Action button or from the Toolbar, when the menu is also long and covers the selection icon.

The only solution I found was to click a little left on the button Action so that the menu appears outside the mouse marker.

Win 10, 20H2, the problem has been around for a long time, it happens with different mice, so I treat it as a bug in the program.
