[orca-list] problem using orca compiled from master and VSCode

[José Vilmar Estácio de Souza <vilmar informal com br>]

Hi all.


Apparently the problem was introduced recently since I can not reproduce 
using version 40.0.


Steps to reproduce:

1. Launch the latest version of orca.

2. Open a file in VSCode-insiders.

3. Navigate in the files using arrows.

4. Change to another window using alt+tab.

5. Change back to VSCode windows using alt+tab.

6. Try to navigate in the file using arrows.


At least in my environment nothing is spoken by orca.

I need to press alt two times to restore the normal behavior.

Thanks.
