What's the current behavior?

When the selection is on an empty block, the delete key behavior is more like backspace.

This causes an odd behavior where the cursor moves to the previous sibling when delete key is pressed instead of staying at the same block. Additionally, delete does not promote the content next sibling block to the current selected block as expected.

What's the expected behavior?

Expected behavior is that delete key always maintains current block selection.

I am not being able to replicate this on a empty block even on the demo, weird

Reproduces in Firefox, Chrome, and Edge.

Interesting, opening the demo on Chrome 62 on OS X, I am not being able to reproduce it

The delete key on a Mac keyboard functions like a backspace key on a Windows/PC keyboard, deleting a character a time backwards from where the cursor is located.

On windows, the delete is a forward delete, so this is doing the wrong thing.

Aha, I see. Sneaky OS X...

Fixed, I believe.
