This is necessary to solve spyder-ide/spyder#13928.
With this we can get all symbols for those files instead of a subset of them.
I couldn't come up with a test for this because we have a lot of customizations in Spyder for the Python language server, but I confirmed this fixes the problem in our side.
Note: I added a test for this on the Spyder side (see spyder-ide/spyder#14119).
