ID 198840 - Undo - Undo Action does not work correctly with 'Set Reference media'

Problem summary

When setting reference media in a project that already has a different reference media set, trying to undo the second 'Set Reference Media' doesn't re-add the previous clip as reference

Customer reported version
nuke.10.0v3

Customer reported platform
centos6

Steps to reproduce

1) Open NukeStudio and switch into the Conforming workspace

2) Import a clip and drag it onto the timeline

3) In the Spreadsheet View, click "Set Reference Media" and choose a clip to import as reference

4) Click "Set Reference Media" again and choose a different clip

5) Undo this action

6) Result: Only the referenced audio track is removed - Reference video track remains the same instead of changing back to what it was before

Reproduced by support
9.0v1, 9.0v8, 10.0v3 on Windows7

Expected behaviour
The second referenced clip should disappear from the timeline and the clip in the Reference video track should change back to the first referenced clip

Actual behaviour
The referenced audio track disappears, but the the second referenced clip stays in the Reference video track in the timeline and doesn't change back to what it was before
