Describe the bug
Was attempting to create some good type stubs and got these errors:

Running mypy for Python 3.8...
*** Testing Python 3.8 on linux
Testing third-party packages...
testing dropbox (31 files)... failure (exit code 1)

stubs/dropbox/dropbox/dropbox_client.pyi:70: error: Definition of "request" in base class "_DropboxTransport" is incompatible with definition in base class "DropboxBase"  [misc]
stubs/dropbox/dropbox/dropbox_client.pyi:72: error: Definition of "request" in base class "_DropboxTransport" is incompatible with definition in base class "DropboxTeamBase"  [misc]

Tracked down the to abstract method signatures in DropboxBase and DropTeamBase being different to that in _DropboxTransport.

To Reproduce
Follow steps in CONTRIBUTING.md for thetypeshed repository.

Expected Behavior

Additional context
Solution is probably to make abstract signatures match the implementation in _DropboxTransport.
