[orca-list] Can't read read-only document in Libreoffice

[Vojtěch Polášek <krecoun gmail com>]

Greetings,
I don't know if this is a Libreoffice or Orca bug, but whenever I for
example receive some document through email, I can't open it right away,
because it is displayed in read-only mode and orca can't read anything
with arrows.
You can reproduce it very easily, just open some read-only document.
Could you please look into it?
Thanks,
Vojta
