* description: parse the translated string as HTML - looking for HTML tags has a performance impact but allows to preserve them from alterations - it also allows to compute the visible translated string length which is useful to correctly expand ot when it contains HTML
* warning: unclosed tags are unsupported, they will be fixed (closed) by the parser - eg, "foo <div>bar" => "foo <div>bar</div>"

* * localizable_html_attributes:
* type: string[]
* default: []
* description: the list of HTML attributes whose values can be altered - it is only useful when the "parse_html" option is set to true
* example: if ["title"], and with the "accents" option set to true, "<a href="#" title="Go to your profile">Profile</a>" => "<a href="#" title="Ĝö ţö ýöûŕ þŕöƒîļé">Þŕöƒîļé</a>" - if "title" was not in the "localizable_html_attributes" list, the title attribute data would be left unchanged.
