The anchor's href is not set, which means that the widget will not
not be styled with the browser's native link styles (such as underline and
font color). Use Anchor(boolean)
to add a default no-op href that
does not open a link but ensures the native link styles are applied.

Note: DirectionEstimator should be set before the widget has any content; it's highly recommended to set it using a constructor.

The object will behave exactly the same as when a widget's

invoked; however the SafeHtml
passed to this method observes the
contract that it can be used in an HTML context without causing unsafe
script execution. Thus, unlike
HasHTML.setHTML(String)

method cannot result in Cross-Site Scripting security vulnerabilities.
