Two additional notes: (1) The dark bar at the bottom is actually transparent, though you can't tell in my attached testcase since I don't have any visible content that traverses it. But you can see this at the original site. (2) Regarding the `mix-blend-mode: darken` piece of this -- "darken" is just an example, but it looks like any non-default value will trigger the same bug in this testcase. (In addition to `darken`, I tested `lighten`, `hue`, and `saturation` in my own copy of the attached testcase, and they all trigger exactly the same results with the dark bar at the bottom of the screen.)
