What Happened?

As the title mentioned, deleting a previous empty block by pressing backspace at cursor position 0 of the next of the previous block will cause current block deleted and the content of this block will be moved to previous block. Because of the behavior, all block-ref to this block will be invalid.

Don't know if it is a feature or a bug.

Reproduce the Bug

The steps are presented at the following screen recording.

Expected Behavior

Should update all block-ref to this block when deleting previous empty block at the beginning of the next block of it. It is intuitive.

can reproduce in Linux

I reproduced it on Windows. I think it is OS-independent.

@Bad3r This issue should be tagged with editor and block-ref.

Here is the code handling backspace keydown when current cursor position is at 0.
