default context, direction none, unicode-bidi override
Test passes if characters are in the same order.

Assertion: In the default context, if unicode-bidi:bidi-override and no direction are applied to an inline element containing mixed direction text, the characters in that element will be displayed in backing-store order from left to right.
= means you should check that the test and reference graphic look the same, except for font differences and cursive joining behavior.
