I would say that is the indented behavior.

If you look at the specification 
(http://dev.w3.org/html5/spec/the-canvas-element.html), regarding 
fallback content, you will find that it is still available when Canvas 
is supported.

For example:
"When a canvas element represents embedded content, the user can still 
focus descendants of the canvas element (in the fallback content)."

Since the content is available, I think it is normal for it to follow 
the normal behavior.
