Disabling drag & drop is not working correctly

[awulkan]

Items disappear under certain circumstances if you disable drag & drop and then drag them.

Steps to reproduce

1. Go to this page: http://hejx.space/vddl-demo/#/nested
2. Click the red 'disable' button.
3. Select the text inside of an item and drag it.

Temporary solution
I managed to get around this by adding this class to my css:

.disable-drag {
  user-select: none;
  pointer-events: none; /* Not needed but prevents visual effect of dragging an item. */
}

And then adding

:class="{'disable-drag': disable}"

To my nested list like this
<vddl-draggable class="group-item" :class="{'disable-drag': disable}"
and this
<vddl-list class="group-body" :class="{'disable-drag': disable}"

What browser?

[awulkan]

Chrome Version 62.0.3202.94 (Official Build) (64-bit).
Firefox Quantum 57.0

Probably all browsers.
Disable drag mode, then select all text and drag the items up and down.

Why the item can be dragged in the disable drag mode?

I don't know, I can take a look at it this week.

It works now.
