CK Editor upgrade chaged line spacing

[gob]

Hi

After running the latest 7.2 upgrade we now have the new CK Editor 5.
However I have noticed the line / Paragraph spacing on all templates and auto-responses has been increased which has changed the look of all email designs.
Also I have noticed that a logo we have embedded in a template response looks really large in the editor view, but looks correct in the received email.

I haven't managed to find any SysConfig parameters for the editor and wondered if anyone has experienced the same and has a workaround?

Thanks
