[end-user] quick fix to make sure label dimensions are updated properly before optimier starts autostepping
[end-user] quick fix to make sure label dimensions are updated properly
before optimier starts autostepping

Current issues:
- Upon domain/style change, the `play` button is disabled
- `autostep` button is still being inconsistent, especially with this
change in place. If `play` also toggles autostep, we need to clarify the
subsequent state changes
- add parallel style into the collection!
- merge changes from master?
