Test style update caused by tree changes with the selector :first-of-type. This test does not use any sibling "~" combinator to avoid its more generic marking.

On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".


Initialy, <foo> is the first of its type, the style should match.

Adding a few elements that are not <foo> do not invalidate the :first-of-type.

Adding a second <foo>. This should breat the rules because the new foo does not match "+ padding".

Adding a few elements that are not <foo>, we should still not match because of the previously added <foo>.
