Fixes misses closing '/' in component declaration

The component declaration 'Component' is missing a now-required '/' on the tag.  As is stands the example fails.

Is there not a better way of ensuring that documentation samples stay up-to-date and correct?  As it's the first port-of-call for people learning a feature, if the examples are wrong, it doesn't create a good experience, especially as one assumes that one's own code is wrong, rather than the example.

Maybe embed a fiddle instead of the raw code?  Then this can be easily tested on each new release.
