NHS A-Z widget - error on serialised DOM check

NHS Website Content API
1

Hi,
The new NHS A-Z widget, replacing the old one that expires in November, throws up 2 errors in a serialised DOM check. As serialised DOM checks are being used in some third-party accessibility checks on GP websites, it’s important that anything the NHS developers release for embedding on GP sites pass these checks without errors.
The errors are…

  1. The allowtransparency attribute on the iframe element is obsolete.
  2. Text not allowed in element iframe in this context.
    The latter relates to the text “Loading...“

The only way to avoid these currently is to rebuild the code without the script, like…

<div>
<iframe id="nhsuk-toolscontent_widget_healthaz_iframe" src="https://www.nhs.uk/content-widgets/health-a-to-z?syndicatorId=9999" style="height: 600px; width: 100%; border:none; background: transparent;"></iframe>
</div>

This works now but if the target loaded by the original script changes, this will break.

This is poor, I have tried down several routes to report this and it appears nobody wants to take responsibility, such an easy change required, that would genuinely help take pressure off Doctors surgeries… Come on, somebody at least acknowledge the problem.
