Tested and confirmed.

Neither can I. The only thing I can think of is to preview the display
equation but that seems like a bad hack for something like this.

Could be. I think leaving it how you had it is fine though. This is only
about aesthetics. The important thing is that thanks to your fix, the
information that the display equation was deleted can now be accurately
conveyed it the output.

One more detail I noticed is that the size of the equation is not
accurate when showing the changes in output. Again, I don't think this
is that important since the information that the equation was deleted is
the only critical thing, but I report it nonetheless. To see this,
compile the attached example file with "show changes in output". The
equations should be the same size.
