Bug 2000042 [wpt PR 55575] - Add an infrastructure reftest for devicePixelRatio, a=testonly
Automatic update from web-platform-tests
Add an infrastructure reftest for devicePixelRatio
While discussions are ongoing about what the semantics should be, and

+This acts both as a pointer to that issue (comments very
+welcome!) and as a warning for those running tests in other
