Steps to reproduce:

Open Word, type some text, including hidden text. To hide text, press CONTROL+D to open the font formatting dialog, then press alt+h to toggle the "hidden" effect. Press ENTER to close.

Press CONTROL+SHIFT+8 to toggle show formatting.

Ensure font attributes is checked in NVDA's document formatting settings.

Actual behavior:

With Show formatting enabled the hidden text is visible. NVDA reads it as any other text, but does not report that the text is set to hidden (as it would for bold or underlined text, for instance).

With Show formatting disabled, the text is hidden, there is no visual cue and NVDA reads the document as if the hidden text did not exist (the correct behaviour).

Expected behavior:

With show formatting enabled, NVDA should report that the text is "hidden" just as it would for other font attributes like italic.

With Show formatting disabled, the text is hidden, there is no visual cue and NVDA reads the document as if the hidden text did not exist (the correct behaviour).
