When spamming around with create folder(and not actually creating it) __new__ named folder is sometimes visible

[ziaulrehman40]

Sometimes when playing around with add folder, this kind of behavior happens.
Trying to pin point when and how it happens, but for now at-least a report of it happens should be made.

We can add reproduction steps and fix it later on.

version: 1.8.0

Here is the reproduction, try to create a folder in a sub folder, don't create it, click outside and click create folder on root, and there you have it.

This issue is actually happening a lot, specially for case when there is no other file and a folder is being created on root
