After adding some e2e tests for 3D texture T2T copy on non-zero mip levels, it turns out that there is a bug in the e2e test itself. The 3D texture copy splitter works well. Bug: dawn:547 Change-Id: I51aef7aaca4caf9c86bfb0590eb0288d17731ba5 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/55144 Commit-Queue: Yunchao He <yunchao.he@intel.com> Reviewed-by: Jiawei Shao <jiawei.shao@intel.com>
