Typically, unterminated command lines for selections using [Next] and [Last] (i.e. [1] [+] [Next]) will still put the selection border around tombstones in the live summary/table. In 3.3 this appears to still be the case as expected, UNLESS the final channel is less than 10.
So for example, [11][Thru][Next] works as expected, but [1][Thru][Next] does not.
[Thru][-] still works as expected.
This is observed on both an Apex 10 and Nomad on Mac.
