Huge .tscn Icon and icon in background of File System panel

[Burloe]

Tested versions

4.3.beta1

System information

Windows 10

Issue description

Using the bottom docked file system in the beta. I haven't had an issue since upgrading until I noticed an .svg icon I made in the background of the FileSystem dock. It's unclickable and doesn't seem to be anything other than integrated into the background. I then tried to swap the item preview style from grid to list, the .tscn of the scene using this icon was massive while all the others were normal.

Other scene files in other folders are normal. The only difference is that this file is a tool script with it's own custom icon. In the 'grid' view, you can see the scene's preview icon as a black square(the scene doesn't have any visual elements in it, only timers) and the icon is a static background.

Also tried docking the FileSystem on the sides and it's present there as well.

Steps to reproduce

Not sure as I don't know what the cause is. But if the cause is that it has it's own icon and/or is a tool script:
New project > Create new folder > Put .svg file in folder > Create new scene and attach script
In script, add:

@tool
@icon("res://New Folder/CloudIcon.svg")
extends Node 
class_name Test

Minimal reproduction project (MRP)

Here's the icon I made in case that's the issue(had no issue in 4.2):
