Windows 10 Mail: catch COM error thrown when Mail app dies and tree interceptor/alive method is attempted (#9392)
* Windows 10 Mail: catch COM error thrown when Mail app dies and tree interceptor alive method is attempted. Re #9341.
Consider the following: a Windows 10 user opens Mail app (hxoutlook), opens a message, then exits Mail app. At that point, tree interceptor/alive method is attempted, but because parent is gone, it raises COM error. Without catching this, NVDA goes silent, so catch this error if possible.
* Update what's new.
