Order running headers
- Order running headers base on weight
- Remove previous running header or ::after content when adding an element
- Merge @page rules
- remove specs pdfs as something in the file changes on every specs run
NOTE: content: element(xyz)
will always override the contents of counter(page)
or content: "hello"
even if those have higher priority, since the element is added in JS and can't yet determine the specificity of other pure CSS selectors.
