--- Comment #2 from zalan <zalan at apple.com> ---
We don't create RenderText renderers for the whitespace/new line only content.

It looks like in RenderTreeUpdater::updateRenderTree
bool mayNeedUpdateWhitespaceOnlyRenderer = renderingParent().didCreateOrDestroyChildRenderer && text.data().isAllSpecialCharacters<isHTMLSpace>();
may need to be updated so that certain parent styles (e.g. white-space) are also taken into account when checking if the text node needs a renderer.
