That's because you've chosen the distant foreground poorly.

Look, you can always shoot yourself in the foot if you intentionally
arrange your colors to produce bad contrast.  That doesn't prove
anything, certainly not that there's a bug or a missing feature.  If
you play with colors, you need to choose them carefully, that's all.
