Might be worth squeezing into the upcoming alpha to have it in 9.5. acat: could you have a look at proposed fix?

The patch looks good to me.

BTW, should we do something about #23805? dom.enable_performance_navigation_timing should not be an issue, but perhaps that ticket can be repurposed to investigate performance.timeOrigin?
