  Log Message:
  -----------
  Handling of text documents does not comply with modern HTML spec
https://bugs.webkit.org/show_bug.cgi?id=244950
<rdar://problem/99719728>

Reviewed by Chris Dumez.

The spec language in https://html.spec.whatwg.org/multipage/browsing-the-web.html#read-text, indicates that Text documents
must be in no-quirks mode: (7.11.4.3 Set document's mode to "no-quirks".)

This is in conflict with the source code in the TextDocument constructor:

  setCompatibilityMode(DocumentCompatibilityMode::QuirksMode);

This causes the following WPT failure:
