Ties remaining after individual deletion of cross-measured ties

Example:

[ 1 ] Fill a measure's end with a chord, and then extend it's duration using 'W' to reach into the next measure. As an example, results are given:

[ 2 ] Delete one of the notes of the chord on the tied chord. Result:

Notice that the tie remains dangling rather than being removed as a result of the tone deletion. Further,

[ 3 ] Delete the top note automatically selected in this example after the last delete, and the tie is deleted this time. For example:

It's as if the top note of a chord is the only tone to have the tie removed following this type of activity, at least on this specific example. It seems that normal behavior should remove any tie associated with any tone, even if the chord/note is post tying rather than before it. Update: Even if the top note is deleted first, the tie also dangles
