See b/141980393 for details.

In the issue, the embedder (assumed to render Flutter contents of size 800 x 600 [1]) is meant to be displayed on its side. To achieve this, it specifies a root surface transformation that translates the surface by its width (or height when it held in the correct viewing position) and then rotates it counter-clockwise by 90 degrees. This test verifies that the Flutter Engine accounts for those transformations in the custom compositor platform view coodinates.

[1] The actual size is something different. 800x600 is for illustrative purposes.
