@covers ::createPlaceholder @dataProvider providerCreatePlaceholderGeneratesValidHtmlMarkup
Ensure that the generated placeholder markup is valid. If it is not, then simply using DOMDocument on HTML that contains placeholders may modify the placeholders' markup, which would make it impossible to replace the placeholders: the placeholder markup in #attached versus that in the HTML processed by DOMDocument would no longer match.
