Simplenote wants to connect to fonts.googleapis.com

### Expected

When launching the app and reading/writing raw text, it is not expected that a third-party connection is establed from the Simplenote application, except to Automattic's own Simperium services when the syncing service is in use.

### Observed

Simplenote wants to connect to `fonts.googleapis.com`.

### Reproduced

* macOS 10.15
* Simplenote Version 2.9

Reproduce the connection on macOS 10.15 with Simplenote 2.9 while launching the app and reading or writing raw text, with syncing disabled. Trace the startup and raw-text paths that initiate the request to fonts.googleapis.com; done means no third-party connection occurs, while Simperium syncing still works when enabled.
