PPSX file

When you open the attached PPSX, in the top right corner you should see an animated reveal of an image of an ancient coin. The image became invisible with
tdf#49247, tdf#101181: output glow and soft edge effects to metafile

Bibisected with linux-64-7.1

Adding Cc: to Mike Kaganski

The document has other issues that will be reported separately. Missing reflection effect is bug 62185.

The example file in pptx format and the image copied

The coin image is inside a group, with a glow effect set: 18 pt size and 60% transparency plus soft edge effect with 50 pt size.

When copied outside the group the image becomes completely transparent as well, even though these settings are displayed on the sidebar.
