ZoomText 2021 prioritises the name attribute over the id attribute when associating labels with inputs

I've previously filed this issue via Sight & Sound in May 2019, but I was doing some testing of some other reported ZoomText issues and it looks like this is still an issue in ZoomText 2021, so I'm filing it here in too in the hope that it might get fixed.

Apologies if this isn't the right place to file this – I can see there's a small handful of ZoomText issues in this repo, although the vast majority seem to be for JAWS.

Summary

Given the following markup, with:

multiple radios buttons - each with the same name, but different ids, and;
where one of the inputs has an id which is the same as the name

<fieldset>
  <legend>Test</legend>

  <input id="foo" name="foo" type="radio" value="foo">
  <label for="foo">
    Foo
  </label>

  <input id="bar" name="foo" type="radio" value="bar">
  <label for="bar">
    Bar
  </label>
</fieldset>

With Reader enabled, with echo turned on for mouse hover, hover over each radio button in turn with ZoomText.

Expected result

As per the HTML specification, the for attribute should reference the label by ID: https://www.w3.org/TR/html52/sec-forms.html#element-attrdef-label-for

As such:

Hovering over the radio button associated with label 'Foo' should announce 'Foo'
Hovering over the radio button associated with label 'Bar' should announce 'Bar'

Actual result

Hovering over the radio button associated with label 'Foo' announces 'Foo'
Hovering over the radio button associated with label 'Bar' also announces 'Foo'
