Exporting selected scenes to HTML5 does not export project audio bus

[gamedevsam]

Godot version:
v3.2

OS/device including version:
Windows 10 v1909

Issue description:
Exporting selected scenes to HTML5 does not export project audio bus file (*.tres). Which means AudioEffectInstance.get_magnitude_for_frequency_range doesn't work on HTML5 unless the user exports all resources in the project, or manually adds *.tres to the "Filters to export non-resource files/folders".

Steps to reproduce:
Create a new project that uses AudioEffectInstance.get_magnitude_for_frequency_range, add a new audio bus, and export to HTML5 by selecting only the scene file.

I should note this is not unique to HTML5, exporting to any platform without manually including the audio bus file will cause it to crash or not function properly.

Can anyone still reproduce this bug in Godot 3.2.3 or any later release?

If yes, please ensure that an up-to-date Minimal Reproduction Project (MRP) is included in this report (a MRP is a zipped Godot project with the minimal elements necessary to reliably trigger the bug). You can upload ZIP files in an issue comment with a drag and drop.

so when I try to export a single selected scene (with dependencies) as HTML it never works for me. The Error for me is, that the singletons were not found. I think Godot forgets to export autoload files with the resources.

Ok here's minimal project:
ReproductionProject.zip

Not sure about other platforms, but it works on Windows and doesn't work on HTML5. The project is for autoload, but bus might have the same problem.

Not sure about other platforms, but it works on Windows

Did you try exporting on windows, or just playing from the editor?

[KoBeWi]

So I just tested again and it works fine in 3.3 rc6, both exported Windows and HTML5 (although I'm able to only test the editor HTML runnable due to some export error).

Can anyone else confirm that it's fixed?

This is not an HTML5 specific issue.

Exporting a game (real exporting! i.e. not play through editor) with "selected scenes" only does not export the audio bus properly.
Tested on both HTML5 and Linux export (current 3.3).
