Description
> Edit: This does actually bring up a good point in your thorough comment. We are setting time and cycle but not dt (via `MFEMSidreDataCollection::SetTimeStep`). @jamiebramwell, does the `dt` every change from the input file value?
Yes - `dt` can change from the input deck value.

Research direction
Start with MFEMSidreDataCollection::SetTimeStep and trace how time and cycle are saved and restored during restart. Read the linked discussion in issue 717 for context. Done means a changed dt is persisted to Sidre and restored correctly after restart.
