Toggling CSS Exclusions on by default has caused the test to fail.
CSS Variables are not working with shape-inside. This was not diagnosed until Exclusions were toggled on by default in 115919, as the test expectation does not enable shape-inside. The expectation ignored the non-variable shape-insides. The test case did not correctly resolve the variable shape-insides.
Working on this. Patch to follow.
