Sample slide (PPTX)

How to repeat:

 1. Open sample document in PowerPoint and Impress. 
 2. Observe how the first line of text appears much larger and shows
    as 18pt in PowerPoint, whereas in Impress it looks about the size
    of the two lines below and 10pt.

Maybe because the Popping Light font is not installed. And the substitution font selected by LO is not a good election.

Poppins is installed. And even if we'd use a replacement font (Arial...)
the size should not be that different.

And I wasn't explicit, in the font selector it literally shows 10pt 
instead of 18pt, too.
