Describe the bug

When uploading a 1.5GB large file using mongofiles with a persistent cursor (parameter useFileBasePersistedCursors set to true), and subsequently downloading the same file with the mongofiles tool, an error "chunk index does not match expected index" occurs. Preliminary analysis suggests that the BsonStoreDestReceiveCore function first triggers the sizeLimitReached condition, resulting in an incorrect initial batch of data being returned. This causes the mongofiles driver to report the error and pause the download.
