Describe the bug
The current implementation of the Native Scheduler component is not affected by the Internationalization configurations applied to it.

To Reproduce

1. Open this Globalization Demo
2. In it, the IntlProvider is defined with a locale value of es
3. Having the above configuration, the first weekday in the Week view should be Monday, while, in the example, the first day is Sunday

Expected behavior
The Scheduler should accept both the Localization and Internationalization configurations applied to it.

Describe the bug
The Native Scheduler allows you to create a new event without setting a title for it. When such an event is created, its delete (X) icon cannot be clicked.

The issue is replicable in scenarios with both default rendering of a custom SchedulerItem.

To Reproduce

1. Open this StackBlitz example
2. Double-click on the Scheduler to create a new event
3. Enter a value in the description field and save the new event

Expected behavior
When you try to delete the event that has no title, you should be able to do it

Workaround
Use the following CSS definition to workaround the bug:

div.k-scheduler-body > div > span.k-event-actions {
  z-index: 30000;
}

Here is a StackBlitz example demonstrating the usage of the above CSS.

Describe the bug
A modal for selecting the editing mode of a recurring event appears on a double click over a recurring event even if the Native Scheduler is not editable.

To Reproduce

1. Open this StackBlitz example
2. Double-click on a random recurring event

Expected behavior
No popups should appear when double-clicking on an event when the Scheduler is not editable.

Screenshots

We've been using the Telerik UI for ASP.NET AJAX Scheduler for years.  It has this nice reminder dialog that can be checked on this link and the below screenshot. 

Can you add the Reminder functionality in the Native Scheduler component?

Describe the bug
In scenarios when we have a color applied to a Scheduler resource, the pre-defined color is not visualized as a background if we use the group prop. This happens when the resource is not available in the array passed to the group property. If the resource that holds a color is available in the group array, the colors are correctly displayed.

To Reproduce

1. Open this StackBlitz example
2. See the 4 events available in the view

Expected behavior
The events assigned to Room 1 should be with blue background and the events assigned to Room 2 should be with red/pink background. This should be valid for all scenarios in the Scheduler - with and without grouping.

Screenshots

Describe the bug
The "ghost" element that appears when we try to resize an event in the Scheduler is missing in the Timeline and Month views. The result is that the users don't have a visual representation of what is the new size of the event they are modifying. The resizing itself is working correctly. The issue is only with the visual representation.

To Reproduce

1. Open this StackBlitz example
2. From the Views in the upper right corner select "Timeline" or "Month" view
3. Select a random event and try to resize it.

Expected behavior
An element that shows the possible new size of the event should appear like it is in the Day view, for example.

It will be beneficial if we have an option to customize the element that appears in the Scheduler when we resize it. Here is a screenshot for more details:
