[BUGFIX 3.12] Backport Symbol fix

[dcyriller]

Port #6389 to 3.12

This solves will close #6389

🚧 We have to re-target this PR against a release-3.12 branch, that need to be created. ⚠️ EDIT: done

@dcyriller release is 3.12 (we only make the release-x-y branches when the specific release is not the current release).

Changed target, and kicked off CI again.

Okay! Thanks

EDIT: These two tests fail. It seems unrelated to this PR though. Indeed, I remember having seen them in another fix for the 3.11 branch:

 33) [Chrome 77.0] integration/adapter/find-all - Finding All Records of a Type: When all records for a type are requested, records that are created on the client should be added to the record array.
     the record array's length is 1

     expected: 1
       actual: 0

257) [Chrome 77.0] unit/record-array - RecordArray: a newly created record is removed from a record array when it is deleted
     precond - record array already has the first created item

     expected: 1
       actual: 0

I opened #6425 yesterday because I noticed the same failure @dcyriller, it is unrelated to this.

We should also backport this to beta
