Impossible to be certain without seeing the code, but your supposition is certainly plausible at least. When I have a control that I know has to behave a certain way, I like to latch onto ARIA attributes so that I can be reasonably certain that if the control looks to be working for sighted users, it is probably working for screen readers.

You can actually see things like this in the W3C ARIA examples. For instance, a disclosure menu widget's JS is set up to "attach" itself to any button with aria-expanded and aria-controls attributes: https://www.w3.org/WAI/content-assets/wai-aria-practices/patterns/disclosure/examples/js/disclosureMenu.js
