Unfortunately we don't have the infrastructure to run tests in real old browsers, so you can either trust me and @romainmenke that it works or you can download Chrome <= 36 and try it yourself! 😅

Fix works in chrome 14-36 (I can't test older versions)

  • 0.1 values indicates it is passing but used to fail, takes a few runs for values to settle back on 1.0
  • values that are still 0.0 are just rounded values (0.04 => 0.0)

No test cases dropped in score.

not going to do further runs at this time as it's a bit wasteful.


edit : just read #14056 (comment)

unsure if we need to wait with rolling this out until we receive more info on that?


Update :

I had to remove the patch from our test suite so posting latest results here :
