Step 3 should read: "Mouse right until the cursor is below Three but still over two, then mouse up. Two should disappear, but doesn't." 35809 3 mitz 2006-03-10 12:49:40 -0800 This test case is a great example of what the comment in FrameView::dispatchMouseEvent() says about not caching the old mouse-over node. In this case, as the mouse enters "Three", the code tries to calculate which node the mouse was previously in, but while doing this, first of all it updates the document's layout applying to the already-updated hover states. According to the new layout, the previous mouse position was in "Four", so "Three Four" is sent a bogus mouse out event, and "One Two" never gets one. 35818 4 jlukas 2006-03-10 14:17:11 -0800 note that this test case works correctly if either the css or javascript hover is removed. only the combination of them brings out this bug. 37065 5 ap 2006-03-20 12:47:09 -0800 Fixed, patch in bug 3439 6989 2006-03-10 11:16:52 -0800 2006-03-10 11:16:52 -0800 Reduced test case test.html text/html 1405 jlukas PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0iVVRGLTgiPz4NPCFET0NUWVBFIGh0bWwgUFVC TElDICItLy9XM0MvL0RURCBYSFRNTCAxLjEvL0VOIiAiaHR0cDovL3d3dy53My5vcmcvVFIveGh0 bWwxMS9EVEQveGh0bWwxMS5kdGQiPg08aHRtbCB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMTk5 OS94aHRtbCI+DTxoZWFkPg08dGl0bGU+PC90aXRsZT4KPHN0eWxlIHR5cGU9InRleHQvY3NzIj4K Lm1lbnU6bm90KDpob3Zlcik6bm90KC5vdmVyKSAubWVudS1pdGVtcyB7CglkaXNwbGF5Om5vbmU7 Cn0KLm1lbnUgLm1lbnUtaXRlbXMgewoJcG9zaXRpb246YWJzb2x1dGU7CgltYXJnaW4tdG9wOi0x cHg7Cn0KLm1lbnUtaXRlbXMsIC5tZW51LXRleHQgewoJYm9yZGVyOjFweCBzb2xpZCBibGFjazsK CWJhY2tncm91bmQ6d2hpdGU7Cn0KLm1lbnUgewoJZmxvYXQ6IGxlZnQ7Cn0KLm1lbnUgLm1lbnUt dGV4dCB7Cgl0ZXh0LWFsaWduOmNlbnRlcjsKCXdpZHRoOjEwMHB4Owp9Ci5tZW51IC5tZW51LWl0 ZW1zIHsKCXBvc2l0aW9uOmFic29sdXRlOwoJbWFyZ2luLXRvcDotMXB4OwoJd2lkdGg6MTUwcHg7 Cn0KaDMgewoJY2xlYXI6Ym90aDsKfQo8L3N0eWxlPgo8c2NyaXB0IHR5cGU9InRleHQvanNjcmlw dCI+CjwhLS0KZnVuY3Rpb24gbWVudV9vbm1vdXNlb3Zlcih0aGF0KSB7Cgl0aGF0LmNsYXNzTmFt ZSA9ICJtZW51IG92ZXIiOwp9CmZ1bmN0aW9uIG1lbnVfb25tb3VzZW91dCh0aGF0KSB7Cgl0aGF0 LmNsYXNzTmFtZSA9ICJtZW51IjsKfQovLy0tPgo8L3NjcmlwdD4NPC9oZWFkPg08Ym9keT4KPGRp diBjbGFzcz0ibWVudSIgb25tb3VzZW92ZXI9Im1lbnVfb25tb3VzZW92ZXIodGhpcyk7IiBvbm1v dXNlb3V0PSJtZW51X29ubW91c2VvdXQodGhpcyk7Ij4KPGRpdiBjbGFzcz0ibWVudS10ZXh0Ij4K T25lCjwvZGl2Pgo8ZGl2IGNsYXNzPSJtZW51LWl0ZW1zIj4KVHdvCjwvZGl2Pgo8L2Rpdj4KPGRp diBjbGFzcz0ibWVudSIgb25tb3VzZW92ZXI9Im1lbnVfb25tb3VzZW92ZXIodGhpcyk7IiBvbm1v dXNlb3V0PSJtZW51X29ubW91c2VvdXQodGhpcyk7Ij4KPGRpdiBjbGFzcz0ibWVudS10ZXh0Ij4K VGhyZWUKPC9kaXY+CjxkaXYgY2xhc3M9Im1lbnUtaXRlbXMiPgpGb3VyCjwvZGl2Pgo8L2Rpdj4K CjxoMz5JbnN0cnVjdGlvbnM6PC9oMz4KPG9sPgoJPGxpPk1vdXNlIG92ZXIgdGhlIGJveCBsYWJl bGVkIE9uZTwvbGk+Cgk8bGk+TW91c2Ugb3ZlciB0aGUgYm94IGxhYmVsZWQgVHdvIHRoYXQganVz dCBhcHBlYXJlZDwvbGk+Cgk8bGk+TW91c2UgcmlnaHQgdW50aWwgdGhlIGN1cnNvciBpcyBkaXJl Y3RseSBiZWxvdyBUaHJlZSwgdGhlbiBtb3VzZSB1cC4gVHdvIHNob3VsZCBkaXNhcHBlYXIsIGJ1 dCBkb2Vzbid0LjwvbGk+Cjwvb2w+DTwvYm9keT4NPC9odG1sPg==
