Event Drag copy enabled even when disabled.

Was looking through the documentation and saw that by setting the copy key to an empty string the copy feature would be disabled.

I tried this and it seems like the copy feature is still enabled. I tested using one of your examples and was able to replicate the bug.

using the example below
https://bryntum.com/products/scheduler/examples/bigdataset-vertical/

I added the following line to the scheduler.
https://bryntum.com/products/scheduler/docs/api/Scheduler/feature/EventDrag#config-copyKey

Set to empty string to disable copying

features: {
        eventDrag: {
           copyKey: '',
        },
    },

After that i held onto the META key and when dragging a task, the task was duplicated.

Branch Name : 7162-eventDragCopy
In the test when using metaKey as an option It doesn't duplicate in the test

        await t.dragBy({
            source   : '.b-sch-event-wrap',
            delta    : [0, rowHeight],
            dragOnly : true,
            options  : { metaKey : true }
        });

But (on Windows) pressing the metaKey (Windows ⊞ Key) and dragging the event, it duplicates that event
