Arrow font-color not overriden when defined twice

[Vahor]

I have a special use case where I import themes files (different collections of images). Imagine a light.d2 and a dark.d2 file.
When I want to generate a image in dark theme. I import both light and dark. dark.d2 will override the light properties if needed, some configuration stays the same.

Which result in something like this:

First style block comes from light.d2 and second style block from dark.d2.

Here I expect the "Arrow" text to be blue as it's defined last ; as it seems that the arrow color is correctly overridden.

I haven't checked every properties.
