// NOTE. This is just a single, basic test of the delays for `interestfor`.
// The `interest-delay-end` and `interest-delay-start` tests take a
// much more in-depth look at *how* the features work, but due to some nuances
// (please read the "NOTE" sections in those tests), they could end up passing
// on browsers that don't actually support this feature. So this test takes
// considerably longer, but should only pass on browsers that implement the
// `interestfor` attribute.
