addSuppressedErrorsToCompactedFailures
Whether compacted failure reports should attach every failed input as a suppressed throwable.
This affects compacted withData, withDataSuites, checkAll, and checkAllSuites reports. The rendered failure message still includes the stack trace of the first failure either way.
null means it will again fall back to TestBalloonAddons.addSuppressedErrorsToCompactedFailures
This property's getter will never return null, but fall back to TestBalloonAddons.addSuppressedErrorsToCompactedFailures.
