View format reinterpretation doesn't work, but its implementation was causing failures on other content. This patch came from: https://dawn-review.googlesource.com/c/dawn/+/84704/comments/339d5a75_5dce5ce3 Bug: dawn:1360 Change-Id: I76adc264d6f185f840d975b46b6e92a0e5a7b4a8 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/86362 Reviewed-by: Austin Eng <enga@chromium.org> Commit-Queue: Stephen White <senorblanco@chromium.org>
