Note outer scroller's size Actual: * Scroller size in step 5 is the same as step 2: Scroller size accomodates the green element when the inner scroller is scrolled all the way up. * Step 7 scroller size shrinks to accomodate the inner scroller which is now the bottommost element Expected: * Scroller size in steps 5 and 7 are equal * As per [this discussion](https://github.com/w3c/csswg-drafts/issues/12898), I think it's intended that the scroller size should shrink as I scroll in step 4. 2148879 1 ap 2025-10-06 16:18:18 -0700 *** This bug has been marked as a duplicate of bug 300266 *** 476987 2025-10-06 14:45:54 -0700 2025-10-06 14:45:54 -0700 Minimum Reproducible Case asc2.html text/html 1090 dshin PCFET0NUWVBFIGh0bWw+CjxzdHlsZT4KYm9keSB7CiAgbWFyZ2luOiAwOwp9CgpkaXYgewogIHdp ZHRoOiAxMDBweDsKICBoZWlnaHQ6IDEwMHB4Owp9Cgojc2Nyb2xsZXIxIHsKICB3aWR0aDogMjAw cHg7CiAgaGVpZ2h0OiAyMDBweDsKICBwb3NpdGlvbjogcmVsYXRpdmU7Cn0KCiNzY3JvbGxlcjIg ewogIHdpZHRoOiAxNTBweDsKfQoKI3Njcm9sbGVyMSwjc2Nyb2xsZXIyIHsKICBvdmVyZmxvdzog c2Nyb2xsOwogIGJvcmRlcjogMXB4IHNvbGlkOwp9CgojYW5jaG9yIHsKICBhbmNob3ItbmFtZTog LS1hMTsKICBoZWlnaHQ6IDIwcHg7CiAgYmFja2dyb3VuZDogb3JhbmdlOwp9CgouYW5jaG9yZWQg ewogIHBvc2l0aW9uOiBhYnNvbHV0ZTsKICBsZWZ0OiBhbmNob3IobGVmdCk7CiAgdG9wOiBhbmNo b3IoYm90dG9tKTsKICBwb3NpdGlvbi12aXNpYmlsaXR5OiBhbHdheXM7Cn0KCiNhbmNob3JlZDEg ewogIHBvc2l0aW9uLWFuY2hvcjogLS1hMTsKICBiYWNrZ3JvdW5kOiBncmVlbjsKICBhbmNob3It bmFtZTogLS1hMjsKfQoKI2FuY2hvcmVkMiB7CiAgcG9zaXRpb24tYW5jaG9yOiAtLWEyOwogIGJh Y2tncm91bmQ6IGxpbWU7CiAgdG9wOiBhbmNob3IoYm90dG9tKTsKfQoKPC9zdHlsZT4KCjxzcGFu IGlkPXJlc3VsdD48L3NwYW4+PGJyPgo8ZGl2IGlkPSJzY3JvbGxlcjEiPgogIDxkaXYgc3R5bGU9 ImhlaWdodDogMTAwcHgiPjwvZGl2PgogIDxkaXYgaWQ9InNjcm9sbGVyMiI+CiAgICA8ZGl2IHN0 eWxlPSJoZWlnaHQ6IDIzMHB4Ij48L2Rpdj4KICAgIDxkaXYgaWQ9ImFuY2hvciI+PC9kaXY+CiAg ICA8ZGl2IHN0eWxlPSJoZWlnaHQ6IDIzMHB4Ij48L2Rpdj4KICA8L2Rpdj4KICA8ZGl2IGlkPSJh bmNob3JlZDEiIGNsYXNzPSJhbmNob3JlZCI+PC9kaXY+CjwvZGl2Pgo8ZGl2IGlkPSJhbmNob3Jl ZDIiIGNsYXNzPSJhbmNob3JlZCI+PC9kaXY+CjxzY3JpcHQ+CmZ1bmN0aW9uIHJhZigpIHsKICBy ZXR1cm4gbmV3IFByb21pc2UocmVzb2x2ZSA9PiByZXF1ZXN0QW5pbWF0aW9uRnJhbWUocmVzb2x2 ZSkpOwp9Cgphc3luYyBmdW5jdGlvbiBnbygpIHsKICBhd2FpdCByYWYoKTsKfQoKZ28oKTsKPC9z Y3JpcHQ+Cg==
