Angle not appears using Sections

I have strange behaviours using Angle within Sections …
Angle seams only works using Safari in special conditions.
Do not work in Firefox and Chrome

I attached a project presenting two sections :
The fist section is very simple : Angle, Margins, one header and two paragraphs.
Result no angles.

In the second one, a reveal Stack contains same stuff as the in first one and Angle appears but only in Safari on computer.


The Angle stack really isn’t designed to be used in something like Sections.

It’s a pity !! :smile:
Thanks for your answer
