Doesn't auto-scroll to bottom in some cases

[nekohayo]

When posting a message with some hyperlinks to images, Srain displays previews of those images, but they end up expanding below the current view, and Srain doesn't scroll to them, so as it is now "un-stuck" from the bottom of the scrollbar, further messages will not appear in the view because they will be below the current "fold", and you need to manually scroll downwards.

I think there are some other cases where this happens (maybe when reconnecting, or something triggering content below the fold somehow?) but I haven't noticed those other patterns yet.

Hi nekohayo, great catch!

Currently Srain only scroll to botoom when message is add. When image is filled to URL previewer (as your said), length of message list changed but Srain doesn't scroll it.

I think there are some other cases where this happens (maybe when reconnecting, or something triggering content below the fold somehow?) but I haven't noticed those other patterns yet.

I haven't thought of this yet, let's fix it when it appears.
