In this example we initially run a transition for 5 seconds, and 2 seconds into its run we change its to-value. In our implementation both the initial and the retargeted transition have the same duration: 5 seconds. However, the retargeted transition should compute its duration by factoring the transformed progress (accounting for the timing-function) of the initial duration when it's interrupted and the transition-duration. 1508946 1 webkit-bug-importer 2019-02-22 01:39:32 -0800 <rdar://problem/48305906> 1954474 2 graouts 2023-05-10 12:59:53 -0700 Works correctly in Safari 16! 362707 2019-02-22 01:39:04 -0800 2019-02-22 01:39:04 -0800 Test case duration-of-a-retarget-transition.html text/html 1313 graouts PCFET0NUWVBFIGh0bWw+CjxodG1sPgo8aGVhZD4KPG1ldGEgY2hhcnNldD0idXRmLTgiPgo8c3R5 bGU+CgpkaXYgewogICAgdG9wOiAwOwogICAgbGVmdDogMDsKICAgIHdpZHRoOiAyMDBweDsKICAg IGhlaWdodDogMjAwcHg7CiAgICBiYWNrZ3JvdW5kLWNvbG9yOiBibGFjazsKICAgIHRyYW5zaXRp b24tZHVyYXRpb246IDVzOwp9Cgo8L3N0eWxlPgo8L2hlYWQ+Cjxib2R5Pgo8ZGl2PjwvZGl2Pgo8 c2NyaXB0PgoKY29uc3QgdGFyZ2V0ID0gZG9jdW1lbnQucXVlcnlTZWxlY3RvcigiZGl2Iik7Cgpm dW5jdGlvbiBkdW1wVHJhbnNpdGlvbkR1cmF0aW9uKCkKewogICAgY29uc3QgdHJhbnNpdGlvbiA9 IHRhcmdldC5nZXRBbmltYXRpb25zKClbMF07CiAgICBjb25zb2xlLmFzc2VydCh0cmFuc2l0aW9u LCAiQSBydW5uaW5nIHRyYW5zaXRpb24gd2FzIGV4cGVjdGVkLiIpOwogICAgY29uc29sZS5sb2co YFRyYW5zaXRpb24gZHVyYXRpb24gaXMgJHsodHJhbnNpdGlvbi5lZmZlY3QuZ2V0VGltaW5nKCku ZHVyYXRpb24gLyAxMDAwKS50b0ZpeGVkKDIpfXMuYCk7Cn0KCnNldFRpbWVvdXQoXyA9PiB7CiAg ICB0YXJnZXQuYWRkRXZlbnRMaXN0ZW5lcigidHJhbnNpdGlvbnJ1biIsIGV2ZW50ID0+IHsKICAg ICAgICBzZXRUaW1lb3V0KF8gPT4gewogICAgICAgICAgICBjb25zb2xlLmxvZygiUmV0YXJnZXR0 aW5nIHRyYW5zaXRpb24gZm9yIG1hcmdpbi1sZWZ0IHRvIDAgYWZ0ZXIgMiBzZWNvbmRzLiBUaGUg ZHVyYXRpb24gb2YgdGhlIG5ldyB0cmFuc2l0aW9uIHNob3VsZCBiZSBtdWNoIG1vcmUgdGhhbiAy IHNlY29uZHMgYW1kIG11Y2ggbGVzcyB0aGFuIDUgc2Vjb25kcyBzaW5jZSBpdCBzaG91bGQgYW1v dW50IHRvIHRoZSB0cmFuc2Zvcm1lZCBwcm9ncmVzcyAoYWNjb3VudGluZyBmb3IgdGhlIHRpbWlu Zy1mdW5jdGlvbikgb2YgdGhlIGluaXRpYWwgdHJhbnNpdGlvbiB3aGVuIGludGVycnVwZWQgbXVs dGlwbGllZCBieSB0aGUgdHJhbnNpdGlvbi1kdXJhdGlvbiBwcm9wZXJ0eS4iKTsKICAgICAgICAg ICAgdGFyZ2V0LnN0eWxlLm1hcmdpbkxlZnQgPSAwOwogICAgICAgICAgICBkdW1wVHJhbnNpdGlv bkR1cmF0aW9uKCk7CiAgICAgICAgfSwgMjAwMCk7CiAgICB9LCB7IG9uY2U6IHRydWUgfSk7Cgog ICAgY29uc29sZS5sb2coIlN0YXJ0aW5nIGluaXRpYWwgdHJhbnNpdGlvbiBmb3IgbWFyZ2luLWxl ZnQgdG8gNTAwcHguIik7CiAgICB0YXJnZXQuc3R5bGUubWFyZ2luTGVmdCA9ICI1MDBweCI7CiAg ICBkdW1wVHJhbnNpdGlvbkR1cmF0aW9uKCk7Cn0pOwoKPC9zY3JpcHQ+CjwvYm9keT4KPC9odG1s Pgo=
