Created attachment 475217 [details] test-hdr-inside-iframe 1. Enable Support HDR Display 2. Open the attached test case Result: The first iframe shows HDR contents for its image. The second iframe shows its image as SDR. Expected: Both iframes should show HDR contents for their images Note: The first iframe is scrollable which means its layer are composited. But the second iframe is not scrollable.
