Mailspring/Snoozed causing sync errors with Zoho Mail

Problem

Mailspring encounters sync errors periodically when syncing Zoho mail accounts. It tries to create the Mailspring/Snoozed folder, which fails as Zoho mail does not allow the user to create a folder with that name (even through the web client).

Context

Sync any Zoho mail account, and the account will error out after an interval. The log shows errors about every 2 minutes, and the account shows an error in the UI every couple of days.
