dmsnell 2ce04ceab9 HTML API: Ensure that NULL and whitespace-only CDATA sections don't forbid FRAMESET.

When CDATA sections (which can only occur inside SVG and MathML content) consist only of NULL bytes or whitespace characters they should not clear the "frameset ok" flag. Previously they have always been clearing this flag, but in this patch the logic is updated to detect these sequences properly.
