godot: Auto Reload Scripts On External Change does not work

Godot version: v4.0.dev.custom_build.5d9cab3ae

OS/device including version: Artix Linux 5.12.8 $ uname -a provides the following output: Linux x1e2 5.12.8-artix1-1 #1 SMP PREEMPT Fri, 28 May 2021 22:51:03 +0000 x86_64 GNU/Linux

Issue description: Editing scripts from an external editor and saving them does not trigger the Godot editor to reload the script. Tried this with neovim within terminal, and also VS Code.

Steps to reproduce: Open the editor settings and set the following:

• General > Text Editor > Files > Auto Reload Scripts on External Change : True
• General > Text Editor > Files > Auto Reload and Parse Scripts On Save : True
• General > Text Editor > External > Use External Editor : True

For neovim:

• General > Text Editor > External > Exec Path : /usr/local/bin/st (I use suckless terminal)
• General > Text Editor > External > Exec Flags : -n TerminalFloat /usr/bin/nvim -c "cd {project}" -c "call cursor ({line}, {col})" {file} – this names the terminal TerminalFloat so that my window manager makes it floating (i3-gaps), launches /usr/bin/nvim (neovim), and issues to neovim the command "cd {project}" and "call cursor ({line},{col})", and passes the filename {file}.

For VS Code:

• General > Text Editor > External > Exec Path : /usr/bin/code
• General > Text Editor > External > Exec Flags : {project} --goto {file}:{line}:{col} – exactly as the docs say

In either case, continue:

• Open a script (new or existing) from the Godot editor – it will correctly open the file in the specified external editor
• Edit and save the script from within the external editor, particularly making changes to exported variables
• Observe that no Output log message appears stating that the script was reloaded, and observe that no changes appear in the inspector to reflect changes made from the external editor

Minimal reproduction project:

An empty new project, with external text editor settings enabled
