I create a new property in a MooseEntity.

isFlag
<MSEProperty: #isFlag type: #Boolean>
<MSEComment: 'An exemplary flag'>
^ isFlag

I do MooseModel resetMeta.

I export the model with the entity containing the flag to an MSE.

isFlag property is absent in the mse file.

Is this a known bug/feature or do I need to update something?
