Went through most of the failing tests and fixed them. Many of the remaining ones fail due to unsupported features that I can slowly whittle away.

It has a couple methods that take closures to make sure that "before" and "after" steps are done together:

Solved the problem mentioned in https://github.com/servo/servo/issues/24724#issuecomment-562326328
