I think one of the most optimistic things to notice about these two images is that Edge amazingly appears to be correct in both cases.

  It's pretty clear that Microsoft really took a close look at the specs when developing Edge, which is really nice. It also has the benefit of being the newest of the major engines.

    Actually, much of the time it comes down to what bugs people report. In a closely related area, IE and Edge both added spread distance rather than subtracting it on inner box-shadows until I reported it last year, then it was fixed in IE within a month: https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/12515080/ https://developer.microsoft.com/en-us/microsoft-edge/platfor.... In this particular case, they may have got the best of it because IE didn’t support outline-offset at all, and so when they implemented it they read the spec carefully. Edge is a continuation of IE. Large swathes of the renderer have been rewritten, but when you do find bugs in Edge they’re commonly shared with IE.

      (Correction: fixed in Edge within a month; IE doesn’t get such fixes. Also “IE and Edge both” should read “both IE and Edge” for increased clarity.)
