Toolbar can render outside of the EditorJS component

[ebrine]

Describe a bug.

Steps to reproduce:
It doesn't happen to me everytime, but sometimes when I use my implementation of EditorJS and I hover over the Editor JS component region just as it's loading, the toolbar renders with a negative top value, so it's way above the first component block.

Expected behavior:

I would expect that the toolbar always appears next to the content block hovered, or not at all.
I think that means that the top value should only be allowed to be 0px at minimum.
