Accessibility false positive aria-label invalid value

[lancegliser]

Describe the bug
I'm using:

<button aria-label="account of current user" />

The accessibility tools report a critical error of invalid value:

Critical
Invalid ARIA attribute value: aria-controls="menu-appbar-user"

The spec for aria-label defines the type as string so any value should be valid.

Same with aria-controls: aria-controls="panel-second" gives an "Invalid ARIA attribute value" on Storybook and addon-a11y both on 6.5.9.
