Steps to reproduce:

• open https://getbootstrap.com/docs/5.2/components/progress/#how-it-works
• read through the content of that section - it includes examples of (ARIA-fied) progress bars
• the first example is a progress bar with a value of 0. the actual element itself uses CSS styling to show the progress bar, and in that case has a width of 0 as well

Actual behavior:

The zero-value progress bar is completely omitted from NVDA's output, despite being exposed correctly by the browser's accessibility tree. Presumably, this is an NVDA-specific heuristic?

Video recording of the current behaviour - note how the first progress bar is completely skipped

Happens in Chrome and Firefox.

JAWS correctly announces the zero-value (and visually zero-width) progress bar.

Expected behavior:

I'd expect the CSS width not to influence whether or not the content is announced - not going by heuristics, but just by what is exposed explicitly in the accessibility tree.
