Loading of script inside .pck does not override autoloaded scripts

[nightrobin]

Godot version:
3.2.2

OS/device including version:

Windows 10 x64

Issue description:

What happened:
Loading of script inside .pck does not override autoloaded scripts
what was expected:
Loaded script inside .pck will override autoloaded scripts

I want to maximize this feature as I plan to have a DLC and updates: https://docs.godotengine.org/en/stable/getting_started/workflow/export/exporting_pcks.html?#summary

Steps to reproduce:

1. Create a script. Print a character print("A") in the _ready or _process. Save it.
2. Register the script in autoload.
3. Export the script to an .pck file
4. Edit the script, change the character print("B") to print. Save it.
5. Create another script to load the .pck in runtime.
6. See if the character printed is "A" and not "B". <- "B" is printed in actual.

I also tried, get_tree().reload_current_scene() after I loaded the pck but it does not have an effect on the autoloaded scripts.

Minimal reproduction project:

Autoloads are defined in project.godot, which is presumably never overridden when loading a resource pack (or if it is, it has no effect since the file is only read once when the project starts).

@nightrobin is there any solution for this?
My .pck also has autoloaded scenes/scripts.
It would be great to add or change them in run-time.
