In an atlas-defined project, a layer that has a rule-based symbology that relies on the $atlasfeatureid will not render upon project loading. The user will have to enter the layer's property window, and click on apply / ok for the layer to start rendering.
A basic scenario that leads to this problem is when a user will use a $id = $atlasfeatureid / $id != $atlasfeatureid set of rule to highlight the atlas feature on the map.
It's a bit of an odd one, so I'll let the attached test project showcase the problem.

Think this should be a blocker, since it's a new feature which isn't working as expected.
I had a go at fixing it by making sure that $atlasfeatureid is set to 0 when an atlas based composition is first loaded, but this fix didn't work since the map has already been rendered by the time the composition is loaded.
I think this global variable needs to be set to 0 when a project is loaded but before any map is rendered.
