Short description of error
When importing an svg file, especially when there are several objects in the file, EEVEE would still display the svg more or less how the drawing looked in the drawing program (Inkscape) without having to manually reorganize the objects to have it look right as shown in the screenshots.
(the svg would be displayed without artifacts when viewed from the direction of the normals)
This is broken in 2.9 where EEVEE displays the same file as seen here
Exact steps for others to reproduce the error
Simply importing an svg with multiple layered objects in v2.90, and viewing them in EEVEE in rendered mode can have them displaying in a weird way.
It is possible to correct this by manually reordering the objects but that can get quite overwhelming in files with several objects.
