Inputfield header dropdown action should be active by default

[Toutouwai]

I attempted to add an inputfield header dropdown action like this...

$inputfield->addHeaderAction([
	'icon' => 'inbox',
	'menuItems' => [
		[
			'label' => 'Create sandbox copy of this page',
			'href' => "/processwire/page/flora-sandbox/create/?id=$page->id",
			'target' => '_blank',
		],
	],
]);

...and was confused when the action was greyed-out and disabled.

It turns out I have to set 'active' => true to avoid this, but shouldn't actions be enabled by default? I would think that if you're adding an action you want it to do something unless you are specifically disabling it for some reason.

Related: please see my request for allowing the target attribute for header actions that are not in a dropdown, as it's not ideal to create a dropdown with a single menu item when adding the link to the action icon itself would be more direct.
