   font-family: monospace;
   text-overflow: ellipsis;
   overflow: hidden;
-  width: calc(5ch + 1px);
-  /* 5ch ought to be enough,
-     but Safari seems to have aliasing issues that make the ellipsis character larger than 1ch by a fraction of a pixel.
-     Adding an extra 1px does not change the validity of the test,
+  width: 9.5ch;
+  /* 9ch ought to be enough,
+     but Safari seems to have aliasing issues that make the ellipsis character larger than 1ch by a bit.
+     Adding an extra .5 does not change the validity of the test,
      and lets safari fit “PASS…” in the space provided.
      This issue may be a bug, but if so, it is unrelated to what this test is testing,
      so no need to force a fail when an easy workaround is available.

-     NB: At the time of writing, Safari fails the test anyway,
-     but I want to make it possible for it to pass just by fixing what is relevant to CSS-UI.
