Automatic reading of incoming console text with UIA is severely broken #10566

CC: @codeofdusk

Steps to reproduce:

Use the terminal with the experimental UIA support enabled.

Actual behavior:

Either incoming text is not read, or old text is read instead of the updated region of the screen. Using the review cursor also doesn't seem to work properly, if I can reproduce this more reliably I'll open another issue.

Expected behavior:

Incoming text is read accurately.
