[Autoembed] Multiple embedding actions are registered in a single undo step.

[Olek Nowodziński]

1. Visit ​http://tests.ckeditor.dev:1030/tests/plugins/autoembed/manual/autoembed
2. Copy embeddable URL, i.e. https://twitter.com/reinmarpl/status/573118615274315776.
3. Focus editable.
4. Hold CTRL+V for a while.
5. A number of links is pasted and corresponding embed requests turn them into widgets.
6. CTRL+Z.

Expected: The last embeddable object invoked is reverted back to link.

Actual: All widgets are reverted back to the chain of links. Sometimes only some group of widgets is reverted. The point is the invocation of multiple widgets is registered within a single undo step.

Absolute edge case ;) Holding CTRL+V or pasting very quickly will cause problems and that isn't a surprise or something that I would be worried.

Replying to Reinmar:

My point was that it might be just a tip of an iceberg, something serious in undo.

Yes and no :D. Depends on whether pastebin is used or not. And autoembed is a special case, because it is asynchronus, so all that multiplies. Ir would be very hard to record all that properly.
