+      # (dd): These packages bumped their MSRV with a patch release.
+      #       As per my understanding cargo will be able to automatically
+      #       resolve the proper version with the resolver v3 which is MSRV-aware.
+      #       With the current MSRV it is not possible to force the resolver to find
+      #       proper versions, hence they are pinned manually here. The end users
+      #       will be able to do the same on their side (which is a bad UX though),
+      #       but apparently there is nothing can be done on the `css-inline` side
+      #       beside bumping MSRV to 1.85 and upgrading to the new resolver.
