Interactive print-it is lost after undoing removal of result

[LinqLover]

To reproduce: print it 2+3, delete the result, Cmd+S to restore.

Expected: Can still click on 5 to inspect it

Actual: Cannot do so (presumably because TextInspectIt is oblivious?)

Discussion: Enabling this would make debugging reference-related issues ("why is this object still referenced?") much harder. However, it could also improve the reversibility and liveness wrt doits in the system.
