Launch Test Status

Regressions are how many fail in the virtual suite while passing in the default.

Passing compares the virtual / default passing test counts.

Failing/Timeout compares virtual / default failing or timeout results

Skipped compares skipped count for virtual / default

• backface-visibility-interop: Need to update tracking for linux only

• controls-refresh-hc: Regressions 0, Passing 58 / 58, Failing/Timeout 0 / 0, Skipped 0 / 0

• css-highlight-inheritance: Regressions 1, Passing 288/ 264, Failing/Timeout 34 / 58, Skipped 11 / 11
