Description
There is now, no easy way to have html in the mask. Previously in GXT 2x we could pass in html which was helpful because we could use a progress gif with formatted text for a message.

Expected result
That we could either pass in html as a message or call maskHTML(String message)

Actual result
any html passes in as a message is escaped

From com.sencha.gxt.core.client.dom.Mask$MaskDefaultAppearance

public void mask(XElement parent, String message) {
XElement mask = XElement.createElement("div");
mask.setClassName(style.mask());
parent.appendChild(mask);

XElement box = null;
if (message != null) {
MessageTemplates messageTemplates = GWT.create(MessageTemplates.class);
box = XDOM.create(messageTemplates.template(style, SafeHtmlUtils.htmlEscape(message))).cast();
parent.appendChild(box);
}

if (GXT.isIE() && !(GXT.isIE7()) && "auto".equals(parent.getStyle().getHeight())) {
mask.setSize(parent.getOffsetWidth(), parent.getOffsetHeight());
}

if (box != null) {
box.updateZIndex(0);
box.center(parent);
}

}

Possible fix
Please provide a maskHTML(String message) function.

In the interim we will try implementing our own mask appearance.
