I'm pretty sure that's a regression, but I don't know when it happened. See the attached testcase. Steps to reproduce: - scroll up and down without lifting the finger, then lift the finger, you should see the touchstart, touchmove and touchend events fire normally. - scroll up and down and lift the finger in-between flings, you should see that no event is fired while scrolling is ongoing. 1932005 1 webkit-bug-importer 2023-02-08 07:07:19 -0800 <rdar://problem/105174606> 1932033 2 gsnedders 2023-02-08 09:17:37 -0800 This reminds me of bug 191218 given the similar summary, but may well be different, especially if it's a recent regression. 464795 2023-02-01 07:06:51 -0800 2023-02-01 07:06:51 -0800 testcase touch-events-not-fired.html text/html 1471 augus.dupin PCFET0NUWVBFIGh0bWw+CjxodG1sIGxhbmc9ImVuIj4KICAgIDxoZWFkPgogICAgICAgIDxtZXRh IGNoYXJzZXQ9IlVURi04IiAvPgogICAgICAgIDxtZXRhIGh0dHAtZXF1aXY9IlgtVUEtQ29tcGF0 aWJsZSIgY29udGVudD0iSUU9ZWRnZSIgLz4KICAgICAgICA8bWV0YSBuYW1lPSJ2aWV3cG9ydCIg Y29udGVudD0id2lkdGg9ZGV2aWNlLXdpZHRoLCBpbml0aWFsLXNjYWxlPTEuMCIgLz4KICAgICAg ICA8dGl0bGU+RG9jdW1lbnQ8L3RpdGxlPgogICAgICAgIDxzdHlsZT4KICAgICAgICAgICAgLmlu Zm8gewogICAgICAgICAgICAgICAgcG9zaXRpb246IGZpeGVkOwogICAgICAgICAgICAgICAgYmFj a2dyb3VuZC1jb2xvcjogcmVkOwogICAgICAgICAgICAgICAgY29sb3I6IHdoaXRlOwogICAgICAg ICAgICB9CgogICAgICAgICAgICBib2R5IHsKICAgICAgICAgICAgICAgIGZvbnQtc2l6ZTogNTBw eDsKICAgICAgICAgICAgfQogICAgICAgIDwvc3R5bGU+CiAgICA8L2hlYWQ+CiAgICA8Ym9keT4K ICAgICAgICA8ZGl2IGNsYXNzPSJpbmZvIj5ubyB0b3VjaDwvZGl2PgogICAgICAgIDxwPgogICAg ICAgICAgICBJbiBXZWJLaXQgaU9TLCB0b3VjaCBhbmQgcG9pbnRlciBldmVudHMgYXJlIG5vdCBm aXJlZCB3aGlsZSBzY3JvbGwKICAgICAgICAgICAgaXMgb25nb2luZywgYm90aCBvbiBib2R5IG9y IGluIGFuIGVsZW1lbnQgc2Nyb2xsIGNvbnRhaW5lci4KICAgICAgICA8L3A+CiAgICAgICAgPHA+ CiAgICAgICAgICAgIExvcmVtIGlwc3VtIGRvbG9yIHNpdCBhbWV0IGNvbnNlY3RldHVyIGFkaXBp c2ljaW5nIGVsaXQuIEV4cGVkaXRhCiAgICAgICAgICAgIGVzc2UgZmFjZXJlIGlwc2FtISBUb3Rh bSBwcm92aWRlbnQgYWRpcGlzY2kgdml0YWUsIGV4cGVkaXRhIGRlbGVuaXRpCiAgICAgICAgICAg IGxhYm9yaW9zYW0gbmVzY2l1bnQgbWFnbmkgZHVjaW11cyB2ZXJpdGF0aXMgbW9sZXN0aWFlIHN1 c2NpcGl0PyBBdAogICAgICAgICAgICBhc3Blcm5hdHVyIHRlbXBvcmUgb2ZmaWNpYSBpbGx1bSEK ICAgICAgICA8L3A+CiAgICA8L2JvZHk+CiAgICA8c2NyaXB0PgogICAgICAgIGNvbnN0IGluZm8g PSBkb2N1bWVudC5xdWVyeVNlbGVjdG9yKCIuaW5mbyIpOwoKICAgICAgICB3aW5kb3cuYWRkRXZl bnRMaXN0ZW5lcigidG91Y2hzdGFydCIsICgpID0+IHsKICAgICAgICAgICAgaW5mby5pbm5lclRl eHQgPSAidG91Y2ggc3RhcnRlZCI7CiAgICAgICAgfSk7CiAgICAgICAgd2luZG93LmFkZEV2ZW50 TGlzdGVuZXIoInRvdWNobW92ZSIsICgpID0+IHsKICAgICAgICAgICAgaW5mby5pbm5lclRleHQg PSAidG91Y2ggbW92aW5nIjsKICAgICAgICB9KTsKICAgICAgICB3aW5kb3cuYWRkRXZlbnRMaXN0 ZW5lcigidG91Y2hlbmQiLCAoKSA9PiB7CiAgICAgICAgICAgIGluZm8uaW5uZXJUZXh0ID0gInRv dWNoIGVuZGVkIjsKICAgICAgICB9KTsKICAgIDwvc2NyaXB0Pgo8L2h0bWw+Cg==
