I was able to break it in a weird way...

I can select the blocks in such a way that I have blocks selected, and I'm editing a single block at the same time. Then, if I press backspace, I can end up merging two blocks instead of deleting them.

@notnownikki Not sure how to reproduce this bug (which browser is this?).

Anyway, the fact that we're storing the selection and the multi-selection in two different reducer is not a good thing and could lead to this kind of bugs, we should make sure to improve these reducers separately (cc @iseulde )

we should make sure to improve these reducers separately

Are you saying we should keep them separate or merge them? I'll have a look at this this afternoon!

@iseulde I'm saying we should merge them so it's one way or another. We wouldn't have the possibility to have a multiselection and a single selected block in the same time if they are stored in the same reducer.

@youknowriad @iseulde this is how I reproduced it. It's probably a "nikkibug" - that is, something I trigger every time, and no one else does until I point it out... 😄

Using chrome.

1. Create three text blocks, with the text "top", "middle", and "bottom".
2. In the bottom block, place the text cursor at the end of the word "bottom".
3. Drag to the beginning of the word "bottom" to select it.
4. Release the mouse button.
5. Move the mouse cursor to the end of the word "bottom".
6. Drag straight upward to select all three blocks.
7. Drag the mouse cursor to the beginning of the word "top" in the top block.
8. Drag the mouse cursor straight down to the bottom block so it is at the beginning of the word "bottom".
   You should see the word "bottom" is no longer selected, and the text cursor is at the start of the word "bottom".
9. Continue dragging upward to select all three blocks. You should see the text cursor is still active in the bottom block, but all three blocks are selected.
10. Press backspace, and the bottom block will merge into the block above it and lose focus.

Further info: this doesn't happen in Chrome 60 or Firefox, but does in Chrome 59 (exact version number: 59.0.3071.109)

Ok, So I think we should merge this and consolidate the selections reducer separately.

@notnownikki Could you open a separate issue the bug then? :)
