Doesn't warn about partially filled out times

[doobry-systemli]

When entering times for the selected dates, there's two usability bugs:

1. Partially entered times are accepted as valid but withdrawn in next step
2. Selecting "Copy and paste times of first day to all other" with partially entered times doesn't create a warning, even though nothing happens

This is a tough one. Browser does not set input's value for an <input type="time"> if user enters only parts of a time. I'm not sure if there is any way to distinguish if the input is empty or partly entered. https://jsbin.com/pikabowoyo/edit?html,js,output

I'm not sure how the following would relate to the UX, but would using multiple fields work?

Hm. Even though I'm a big fan of using the browser native input elements as much as possible. Together with #238 this kind of begs the question whether to switch to some form of custom element for date and time inputs. 😿

I've asked on StackOverflow and got a solution after a few minutes. The input is invalid if partially filled. 🎉

Reopen as the fix does not work in Firefox on Desktop. 😞

User interfaces of mobile Chrome, mobile Firefox and Edge prevent filling in a partially time. Safari (Desktop) and IE 11 does not support <input type="time">. Haven't had the chance to test iOS Safari yet.

Yeah, just experienced the same: it doesn't work as intended in Firefox on Desktop 😞
