LPS-35836 Moving pop-up dimensions back inside the dialog

Hey Eduardo,

I moved the dimensions outside the dialogs in the export-import component to get the height and width working, but it seems you've fix the bug so I've moved the dimensions back to the dialogs again. 

I noticed that the toolbar with the button is not fully displayed. Is this a bug or do I have to change anything in my configuration?

Thanks!
