We can use internals.selectedTextForClipboard() to verify what we'll put
text/plain into clipboard.

The plain text has the additional space so I will fixed it.

Since StyledMarkupAccumulator::renderedText() calls plainText(), it is better to
have gTest rather than layout test.
The benefit of layout tests is that they can run at all browsers. But this
layout test runs only on Blink based browsers.
Also, "paste" command does some magic at inserting HTML fragment, we want to
isolate "copy" issue and "paste" issue.
