While working on #4340, I took a closer look at the Calendar tests and saw potential for separating the DOM code from the logic that builds the time text.
I extracted the time-formatting logic from
calendar.jstocalendarutils.mjsso it can be tested directly with unit tests. That let me replace 8 E2E tests with unit tests, which I find easier to understand. They are also faster. The remaining E2E tests still cover the whole path.I think there is more potential in this direction (e.g. the
dateheaderspath), but this PR is already big enough.
