HtmlComponent.setTitle() doesn't format HTML-Tags

I’m currently updating a vaadin 8 app to vaadin 23, and we we’re using the setTitle() method to display tooltips.
In v23 it looks like the String doesn’t get interpretted as HTML anymore, because the HTML-Tags just get displayed and aren’t interpreted.
I can work around linebreaks with unicode but I don’t know a way to set Text bold for example.
Is there a work around or is it just not supported anymore?

It’s not supported anymore. setTitle just referring to the default html title attribute.
