Re pro steps:

1. If you have Yahoo! Mail account, login into "Classic Mail" and open the list of messages.
2. Pick one of the messages, open it and press the "forward" button to open the "forward" screen.
3. Skip directly to the multi-line "message body" field, turn on "virtual buffer pass through" feature and start reading with up and down arrows.

Result: you will notice that the reading will stop right after the line that says "on [date] so and so wrote".
Pressing down arrow after this point will produce silence and nothing will be read.

Using NVDA Navigator (via numpad keys) one can find that the following text is embeded into something called "section editable"; I believe, this is actually a blockquoted section.
