Florian, what's your take here?

We are not updating the list of possible windows to share after the permission prompt has been displayed. If we wanted to update the list whenever a new window opens (or changes title), we would need the platform code to send a notification when it happens.

Also, this bug seems familiar, so I wouldn't be surprised if it was a duplicate.

Couldn't we just execute the code that populates the list on-demand when the drop down is opened?

It would be nice, but I'm afraid that would cause UI flicker, due to needing to send a message to the content process and wait for the reply to update the list.
