Presentation exhibiting the bug (red text is shadow; play animation!)

If I have a transparent text box with some text and a shadow effect, and apply an "Appear" animation effect to it - the shadow appears before the actual shape appears.

The red shadow is visible when you start the presentation (it should not be visible). Then the black text appears on click.

Apparently different results by different people

Note: Red text is the shadow effect. 

I initially read this as the shadow (red) renders first (in time) before black text as in comment 1 when pressing F5 and go through the sheet. This doesn't happen in my case

However the red shadow is in front of the main text, but it should be in the back

So or comment 1 a mistake; or there are 2 bugs

Seems like two bugs - but might be two manifestations of the same problematic code. What OS and VCL are you using?

I get the black text already is displayed on the shape and the red shadow text appears.
If I set 'Group Text' to 'As one object' instead of 'By 1st level paragraphs', then nothing appears, but black text and red shadow text are immediately displayed.
