fix case when mouse leaves the handle

[renardeinside]

hey @NiclasDev63 ,

First of all huge thanks to you for your work on this project - this really saved me ton of time!

I've found a small peculiar behaviour which looks a bit inconvenient. i can formulate it like this - when the mouse moves over the handle and leaves it, the handle is still not hidden.

I've introduced this small PR to fix it, but not a frontend expert, so maybe some corner-cases are not covered.

The problem if we use your solution is that the user has to hover over the drag handle every time before leaving the editor with his mouse to make it disappear. However, the drag handle remains visible even if you move the mouse from a line within the editor directly to a component outside the editor, which is why we should attach the event listener to another component e.g. the editor.

@renardeinside Just pushed a few changes that should fix your problem. If everything works as expected, I'll publish the new version on npm.
