This is not the issue. Please look into what arunp99088702 has just said.
I'm sorry, but I'm not looking for values persisted. I'm looking for initial property values missing.
Please, re-try the scenario with newly added component and without clicking the check mark.
The scenario we are talking about is when you add a list component (or any component with style system), check initial dialog values and simply close the regular dialog, apply a style and then re check the initial values in regular dialog.
