<pre>Simple line layout: Ignore -webkit-flow-*content while collecting text content for innerText.
https://bugs.webkit.org/show_bug.cgi?id=145344
rdar://problem/20959522

Reviewed by Antti Koivisto.

This patch ensures that when a -webkit-flow-into content is present in a simple line layout container,
we skip it while collecting the text content for innerText.
It's not always guaranteed that a simple line layout container only contains simple text nodes. In such cases,
we need to ensure that text offset computing only takes the simple text nodes into account.
