I did `> 10` but in fact it should be `> 0` or just a simple `assert.ok(wid.content)`; I did that just to make sure it's not collapsed - if element has `display:none` the `scrollWidth` and `getBoundingClientRect().width` will both be zero and pass the the other assertion, even tho it's wrong since user won't be seeing anything.

the unit tests already check the length of the string, and the `innerHTML` might contain other elements in the future (eg. `Dec 23, <em>Sunday</em>`) which doesn't overflow but would fail since it has 23 chars. - I decided to do this way to avoid updating the tests later.

I'll update the test just to make it clearer and add a note about the why.
