fix:3065: hide reports where 0% leaks where blocked.

        val blockedLeaks = calls - leaks

        val blockedRate = blockedLeaks * 100 / calls

        if (blockedLeaks == 0 || blockedRate == 0) {

            // Hide cases where tracker blocking is disabled, because wordings may be confusing.

            return

        }

        val blockedRateStr = blockedRate.toString()

        val blockedLeaksStr = blockedLeaks.toString()
