Mouse event fired incorrectly when NVDA is paired with firefox

[stevenbriscoeca]

This bug has been found in this repo ten1seven/what-input#68 (comment). It might be NVDA causing it.

Steps to reproduce:

Notes : Use NVDA and firefox.

@ten1seven created this codepen to test: https://codepen.io/ten1seven/pen/yzPYrb?editors=1010

• Open the console
• Navigate by keyboard to the checkbox with your keyboard
• Use the spacebar to toggle the value of the checkbox

Expected behavior:

In other browsers, you should see the keyup/keydown events firing, but with NVDA+Firefox only mouse events fire, even down to the checkbox itself. (comment taken from ten1seven/what-input#68 (comment))

System configuration:

NVDA version:

2017.2

Windows version:

Microsoft Windows 7 [version 6.1.7601]

@StephenBe is this issue still reproducible in NVDA with last Alpha?

Probably the same as #4903. In browse mode, space/enter is overridden to activate (which is a click for a checkbox).

@jcsteh does it mean that in focus mode this should work as expected?

[jcsteh]

Yes.

[Adriani90]

I don't see a difference here between Firefox and other browsers like Chrome or Edge.

@jcsteh given that such custom key events are mostly meant to work in focus mode rather than browse mode, is it ok to close this? Or is there a use case for this to work in browse mode as well?

[Adriani90]

I am closing as per comments above.
