circle-sort-key/literal render test fails locally on macOS

[mourner]

@ahk circle-sort-key/literal render test (introduced in #8467) fails for me locally, apparently because of some minor precision differences that make the debug line shift by 1 pixel:

@ahk could we remove debug: true from the test? Or maybe shift the center slightly to make it consistent across platforms?

Could it be helpful to just make the test pixel dimensions bigger? Ideally it's very obvious that cross-tile interaction is important in the test. Do you have any tips on how I can verify I made this test more robust?
