5.4.4.1. [Critical] Writer-side filtered samples not always marked as acknowledged when application acknowledgment was used

When application acknowledgments were used in conjunction with ContentFilteredTopics, samples that were writer-side filtered were not always immediately marked as acknowledged. This problem, which was documented as fixed via RTI Issue ID CORE-6132 in previous releases (such as 7.3.0), was not completely fixed in those releases. Specifically, DataWriters failed to acknowledge writer-side filtered samples when the DataReader used a filter expression that was based only on key fields or only on metadata fields. This problem is now fixed, and DataWriters now always mark writer-side filtered samples as acknowledged.
