Problems inferring type of variables in an autoloaded node's script at runtime

Issue description

I noticed that type inference does not work under very specific circumstances: when inferring the type of properties of a script that is attached to the root node of an autoloaded scene via the global autoload name within the script itself, or within another script that is used by the autoloaded script. The problem only occurs at runtime - in the editor the lines are shown as being typed and autocompletion works as well, but when running the project it's as if type inference did not work at all. See the reproduction steps and MRP below.

Screenshot showcasing the error described above, type inference works in the editor but fails and causes a crash at runtime.

Steps to reproduce

Add an "autoload" scene to the project
In the root node of that scene, attach a script
In that script, add variables with types
Also in that script, write functions where the type of those variables is being inferred (using the global autoload name)
Alternatively, do that in another script that is loaded by the autoloaded node's script
It works in the editor, but at runtime you will get warnings / errors

Sounds the same as:

Ah yes, that does seem to be the same issue!
