Description

Describe a bug. I've created a drop zone to upload files. After the file is uploaded the block is highlighted blue. (In screenshot below). How do I stop this from happening ?

Expected behavior: Uploaded photo shouldn't have the blue highlighted box around it because I don't want the block to be selected.

Screenshots:

Device, Browser, OS: Chrome

Editor.js version: Latest version

Research direction
Look into the drop event handler for file input and find where block highlighting is triggered. Check if there is a way to prevent the default selection behavior after file upload.
