Bug: clicking outside of an editor should clear currentBlock (call dropPointer) even if selection was inside of editor before the click

[VikhorKonstantin]

Describe a bug.

Steps to reproduce:

1. Go to example_dev.html
2. Click on somewhere outside of the editor
3. Press '/'

Expected behavior:
Toolbox shouldn't be opened, because I've already went out of the editor by clicking outside

Actual:
Toolbox is still opened because we haven't cleared currentBlock

Device, Browser, OS:
Any

Editor.js version:
2.29.1

Seems like its works only on a second click. Need to debug this code in the ui.ts
