Sets or gets the contents of a text element using standard HTML.
Setting the html property sets the text and styling of
the text element. You can use a subset of HTML tags and CSS attributes
as described above. Any text that the element
already contained is replaced.
Getting the html property returns the element's text, including
HTML tags.
The html property maps the Editor's built-in text themes and custom
formatting to HTML and CSS as described here.
To set or get the plain, unstyled contents of a text element, use the
text property instead.
