The Feedback Hub app is the best way to report issues to Microsoft, and I am virtually certain that there is an Accessibility or Ease of Access category, perhaps both, that you can put something under.
It's also always worth doing a search in the Feedback Hub to see if someone else may have reported the same issue and up vote it and/or add comments to it.
