[orca-list] bug orca with alt+tab and ponctuation

[Jérémy Prego <jeremy pregonetwork net>]

hello,

Environment: orca master + speech-dispatcher master

when I use alt+tab to switch between windows, orca does not keep the
mode of punctuation that I chose in the preferences, but switches to
none, as long as I keep the alt key pressed.
it raises concerns when using the latest version of speech-dispatcher,
because the . and the / are no longer read in the titles of the windows
that contain them

Steps to reproduce:
1. In Orca preferences, set punctuations level to some;
2. Open a document in Pluma : e.x: pluma /tmp/blabla.log
3. Press the shortcut to announce the window title;
4. Press alt+tab until the previously opened window title is pronounced

Actual result: Orca pronounce the title as it would in punctuation level
"none" : e.x : pluma tmp blabla log
Expected result, same punctuations should be pronounced: e.x: pluma
/tmp/blabla.log

thanks,
