Markup doesn't work in attributes

[magnus.carlsson@…]

I can use ${Markup(data)} to avoid escaping in most cases but when I try to use it in a attribute it is ignored:

<div title="${Markup(data)}">${Markup(data)}</div>

will produce something like this if data = "Text Text"

<div title="Text&amp;nbsp;Text">Text&nbsp;Text</div>

My main use case or this is to include   in the tooltips.
