Firefox and Safari don't remove the style when a paragraph is dynamically added
between the <pre> and the test paragraph.
Selects an adjacent element.
Testsheet:
pre + p {color: red;}
The pre + p selector means "each P element that is preceded by a PRE element".
So this paragraph should be red and the other P's on the page shouldn't be.
This paragraph should not be red.
Insert paragraph after <pre>.
Are all styles updated correctly? They aren't in Firefox and Safari.
