JAWS is announcing the disabled state of the button twice

Can't name the build that introduced this one — I haven't hit this exact regression myself. But the pattern (announced once on the control, then again on the inner text) usually means the text node inside the button is being exposed separately from the control, each carrying the state.

Two quick tests to narrow it: try NVDA and see if it doubles up there too — JAWS-only points at a JAWS interpretation change, not the published output. And check the Focus Order dialog for custom accessible text that duplicates the on-slide text.

If it's consistent across readers, I'd file it with support. "Announced once before, announces twice now" is exactly the kind of regression they're responsive to — note your JAWS version and Storyline build when you do.
