Problem/Motivation

Hello, we are updating from 4.0.3 and noticing that there might be a bug with 4.1.3 in the `setInitialDuration` function where the strict equality operator (`===`) is used when comparing the `duration` variable to the value `0`.

Steps to reproduce

  1. Go to https://simplytest.me/
  2. Select "Smart Date Starter Kit"
  3. Edit the Smart Date field at "admin/structure/types/manage/event/fields/node.event.field_when"
  4. Add `0|Ongoing` to allowed duration values
  5. Set default duration to `0`
  6. Add a new event "/node/add/event" and notice that `time-end` is visible
  7. Change duration from "Ongoing" to "30 minutes" and then switch back to "Ongoing"
  8. Notice that `time-end` is hidden only after making the switch and not on the initial page load.

Expected Behavior
The end date and time fields should be hidden when the "Ongoing" option is selected on page load.

Proposed resolution

In 4.0.3 the code worked when the equality operator was `if (duration == 0)`, however the`setInitialDuration` function in 4.1.3 has the condition `if (duration === 0)` is now strict and doesn't seem to work with 0.

To fix this issue, should we convert the duration value to a number before comparing it to 0?

if (+duration === 0) {
  // Call this to hide the end date and time.
  durationChanged(element);
}
