| Safari on macOS runs with "isolated tree mode" enabled, whereas embedded WebKit on macOS |
| and other platforms all run without that mode, which we call "live tree mode". |
| |
| To ensure test coverage, we have a duplicate of nearly every test in this isolated-tree |
| directory to ensure that running layout tests covers both modes. |
| |
| The only difference is that these tests should have a directive at the top to enable |
| isolated tree mode, and relative paths may be updated. In rare cases expectations might |
| be subtly different, but in general that should be considered a bug and expectations |
| should be aligned. However, slightly wrong expectations is better than no coverage at |
| all. |
