<svg> elements with an img role must have an alternative text

aaron.ferris → made their first commit to this issue’s fork.

Added a condition to use the role and aria label should a title be defined. If not, no role, no title and no aria label.

I am not sure that removing the `role="img"` from svgs that do not also contain a title, necessarily make that module more accessible.

I suspect we may need to also remove the item from he screen readers output to avoid confusion.

Without a role img it may pass check for missing alt text, but it seems to me to be a workaround of the testing tool.

Perhaps a adding `aria-hidden="true"` would help. ref: https://www.unimelb.edu.au/accessibility/techniques/accessible-svgs

Yes thats a good idea, pushed a change.
