[sianford]

Description

Reproduction

Steps to reproduce

1. Open the Textbox Disabled story in Windows.
2. Open NVDA with the Speech Viewer switched on.
3. Click on the content of the disabled Textbox field.
4. Inspect the Speech Viewer window.

Expected result: There is no response when the field is clicked on. This is not accessible at all using the keyboard (which is expected behaviour).

Actual result: The Speech Viewer states the field is "clickable".
