In the properties dialog for a folder, the "not checked" state for the "read-only" attribute is not reported at change

[k-kolev1985]

Steps to reproduce it:

1. Open Windows Explorer.
2. Select a folder with some files in it. Maybe some of them should be with a read-only attribute and some - not, but I'm not sure that it is required for reproducing the bug.
3. Press Alt+Enter to invoke the properties dialog for the folder.
4. Move the focus to the check box for changing the read-only attribute.
5. Press space a few times to change its status between checked, half-checked and not checked.

Expected results:
NVDA should report all status changes for the check box.

Actual results:
NVDA stays silent when the state of the check box is changed to "not checked".

Note: In order to reproduce this, the check box in question has to have 3 states: checked, half-checked and not checked. If it has only 2 (checked and not checked), NVDA will report both states as it should.

Test environment:

• Operating system: Windows 10 Pro (build 14393.693), 64-bit, in Bulgarian with all locale settings set to "Bulgarian".
• NVDA version: next-13899,af44c1d4.
• Processor: Intel Core i5-2320 at 3.00GHz.
• RAM Memory: 8.00GB.
• Graphics: Palit GeForce GT 630, 1024MB dedicated memory + 3071MB shared system memory, desktop resolution set to 1920x1080.
• Sound Card: Realtek ALC662 at Intel Cougar Point PCH - High Definition Audio Controller.

Thanks for raising this, and for providing so much information! I can reproduce this with next-13899,af44c1d4.

Assuming this is a quick fix, I will assign this a priority 2.

Really quick way to repro this:

1. Open this URL in Firefox: data:text/html,<div tabindex="0" role="checkbox" aria-checked="mixed" onClick="this.setAttribute('aria-checked', 'false')">Test</div>
2. Press enter on the check box in browse mode.

• Expected: "not checked"
• Actual: Nothing.

Implementation hint: this needs a tweak to speech.processNegativeStates. For REASON_CHANGE, if HALFCHECKED is present but CHECKED isn't, we should make sure we add CHECKED to speakNegatives.

@feerrenrut This seems prime for a goodForNewDev label, no?

@derekriemer yeah I think so.
