Quill 2's getSemanticHTML() serializes every space as U+00A0, turning a whole paragraph into one unbreakable word that stretched the survey cards far past the viewport. Normalize to plain spaces when sanitizing (which also heals existing records on every output) and when the editor writes the serialized HTML back into the textarea.
