The image log render tests uses an EXR that contains INF. Workbench
with specular enabled will mix these INFs, but there is a difference
in behavior between OpenGL and Vulkan.
In OpenGL mix(0.05, INF, 0.0) will result in INF
In Vulkan this results in NaN.
This should eventually be solved in the engine to ensure consistency.
For now we disable the render test and document the limitation.
