There seems to be an error in this deployment in regards to <img> elements.

On the 06 August 2024 Deployment (IBM 7.2, 7.3) I'm receiving the error:
Element <img> with "img" role has no accessible name
even when the img element has an alt tag.

Changing the rule set deployment date to:
07 June 2024 Deployment (IBM 7.2, 7.3)
results in this error not being shown, so it's definitely part of the 06 August 2024 Deployment.

The release notes for August 06, 2024 (https://github.com/IBMa/equal-access/releases) don't indicate any change to the reviewing of img elements, only svg_graphics_labelled. So there doesn't seem to be a reason for <img> elements suddenly showing up in this review.
