Kind of like a <span> in an HTML text paragraph can contain arbitrary DOM elements. It would be useful to embed views within a label's text.

Needed for  Issue 576531  (an image inside flowing multiline text). Would also be useful in, for example, the fullscreen banner where I have a bordered view inside a single line text (I currently use a BoxLayout, which works because its just one line of text, but it would be neater to use a StyledLabel with a nexted view).

It isn't that hard to do, actually, because of the way StyledLabel works internally.
