Can select disabled component with "Select All" button

Having issue installing a component with symlinks on windows platform, I disabled it from installer using platform information.

function Component()
{
    // constructor
	if (installer.value("os") === "mac") {
		component.enabled = true;
	} else {
		component.enabled = false;
	}
}

The component can not be selected using the mouse or keyboard, but if you click on "Select All" button, it is then selected and tried to be installed. In my case the installer will then failed because component can not be safely installed on this target platform.
