      On 4.4 an update command with update modifiers silently does not perform an update. Please see the test script in "Steps to Reproduce". Field "str_e" does not get updated. In version 5.0, the same command fails since the field to be inserted starts with character $. In version 5.0, when feature flag for https://jira.mongodb.org/browse/PM-1856, which will permit "$" prefixes in field names, the field "str_e" gets correctly updated.

      I believe 4.4 version should work in the same way as 5.0 without "$" prefixes in field names enabled - that is, fail to insert.
