- Consider adding a brief comment above the isVisible function to explain its purpose in determining element visibility for ARIA processing.
function isVisible(element: Element, options?: { forAI?: boolean }): boolean {

- [nitpick] For consistency with other test names, consider renaming the test title to begin with 'should', for example: "should show visible children of hidden elements".

I am not sure how this makes sense. Also, you can't process children as if they are visible. And we probably only want this for non-aria visibility.

How so? As in, you're surprised how Chromium and this issue interpret the ARIA spec, or as in this code is weird?

I think we can, because the isVisible method takes parent elements into account when determining visibility.

It already does so, based on my reading of isElementHiddenForAria. I added a test in 9775c4a to ensure that.
