I took the test case from WHATWG and changed it into JSFiddle:

Link - https://jsfiddle.net/1hqr2spL/

These are results across all browsers:

*** Safari 15.6 on macOS 12.5 ***

before: rgb(255, 0, 0)
after: rgb(255, 0, 0)
load: rgb(255, 0, 0)

*** Firefox Nightly 105 ***

before:rgb(255, 0, 0)
after:rgb(255, 0, 0)
load:rgb(255, 0, 0)

*** Chrome Canary 106 ***

before:rgb(255, 0, 0)
after:rgb(255, 0, 0)
load:rgb(255, 0, 0)

_______

Is something else needed here? Thanks!

Test

In a standalone file, WebKit logs:
before: rgb(0, 0, 0)
after: rgb(0, 0, 0)
load: rgb(255, 0, 0)

whereas other browsers log:
before: rgb(255, 0, 0)
after: rgb(255, 0, 0)
load: rgb(255, 0, 0)
