WordPress 5.5 introduced several improvements in the accessibility of the Media component.
Improvements in the accessibility of the status and error messages in the Image Editor
On previous WordPress versions on the Edit Media page, when activating the “Restore Image” button, a message was shown above the image while the Restore button itself disappears.
Since the button would have been focused at the time when activated by keyboard, this causes the keyboard focus position to be lost and reset to the top of the page.
The message itself is also not announced by screen readers, and may not be visible
