Make openQuickViewScrollText robust

The QuickView text <webview> provides no signal that it is loaded, but
it does have a src attribute. That can used as a proxy for loaded, and
help make a test that is robust (to load / script timing) on the bots.

 - make the text <webview> selector precise (.text-content class)
 - change the text scroll test to check the webview src attribute
   is non-empty before proceeding.
 - change to use scrollBy, and send incremental scrolls until the
   the scroll limit is reached [1].

[1] if the bot misses or drops a JS scrollBy request, no problem: just
ask for it again.
