Double-click-plus-drag opens unwanted new file

[michaeljsalo]

Issue Type: Bug

In VSCode for Mac OS, I'm experiencing a problem where the file explorer keeps wanting to create blank new files.

Steps to reproduce:

• Double-click on a file name, in the file explorer
• During the double-click, move the mouse slightly up or down
• A surprise blank new file opens at the bottom of file explorer

This happens to me all the time by accident. It has never been intentional, and I don't see any clear reason why I would want this behavior. Please investigate. Thank you

We did this to allow double click on empty explorer space to create a new file. This is aligned with some other views - for example the Watch view.
This has never happened by accident to me thus far. Though let's keep this issue open to gather more user feedback and if it happens accidently more often we should either prevent double click to create a new file, or try to be somehow smarter about it.
