In the attached test case, moving the mouse cursor over both the green and the red dot at the top left of the yellow circle should make it appear on a green background (via CSS :hover). However, if the yellow circle is a region, the mouse events will propagate to its parent only over the would-be-rectangular border (green dot) and not inside the area between the rectangular border and the actual circular border (red dot). 889218 1 mibalan 2013-05-15 02:30:11 -0700 On closer inspection, this doesn't look like a bug anymore - the same behavior happens without regions: children of an element with rounded borders will still receive mouse events even when the mouse is outside the rounded rectangle (but inside the "real" rectangle). The lack of "reaction" when moving the mouse over the red dot in the actual file comes from the fact that the named flow contents "eat up" the mouse event and it never bubbles to the region (at least in the current event propagation model). Closing as RESOLVED/INVALID :) 191255 2013-03-04 09:00:42 -0800 2013-03-04 09:00:42 -0800 Ref-test highlighting the problem region-background-clip.zip application/x-zip-compressed 1647 mibalan UEsDBBQACAAIABOWZEIAAAAAAAAAAAAAAAAkABAAcmVnaW9uLWJhY2tncm91bmQtY2xpcC1leHBl Y3RlZC5odG1sVVgMAHrQNFFl0DRR9QEUAJVUW2/TMBR+Tn/FIQgJJLJ0l44tSyulazu6C1MvGZQ3 Jz5LDE4c2c6yDvHfcZJ2GxMS4JfjfD6X73w+jv+KilivC4RUZ3zQ8WsDnORJ38bcrgEkdNCx/Aw1 gTglUqHu2+Fy4hzZNa6Z5jiYY8JEDhGJvydSlDmFmLMC8L7AWBNtzny39TQhSq+bTQE/OpaVEZmw 3IPuScf62elYO7oSDhVaNadPGT0oJX9rU6KJxzKSoFvkyUlEFB4evGc3w+t51b04S0Rg1qdFmI7D xOxO688gOQ1WxgwfMJfdGpiP+Xh2Mz/YK/eXatYNpkE1mq2Og8rtjVRwdpnS2XyyCr+JpXtOo8Nz fkUwXOCXvf2JHAbjsf54NEwm9JJJ+fngeDUNklS4lckyia9HiywtcX/5tRc2xRfhzfX8one6mk77 9jvIhSOxQKI3/b4uiMRcN91WjOrUg90P3eLeHFspsiTVz4CtWLuYbcNlK/3z8N7L8C0QCUlROpJQ VioPet03T6hxM16gBGcUIm50P/lNfycWXBivNXIuqvpM3KG8NXsPUkYp5g2jR0JFzehW5Nq5JRnj aw+CtGHdgoo9oAd7G2Kc5eg80t00Zz2K46V1rRcDsSXE66hE4paA724GzHfb4fUjQdf14Akz4Zbl cza4MvlgLUoJmSgVQpNepwhNHjDjBxGa1nZgacC2ZYiZjDmCSkXJjUQIlKmCkzVSMP2SlsgmwxPN Hd81Bf9WV5ok/1JVacb5f9f23aZ1n7I7YLRvt6ra5pESpfr29sXZDc2tU3uPDWb5xeDeLD+Sf7Zu 0YS6JrYp11jfbYU391D/XH4BUEsHCKzBzNJsAgAAbAQAAFBLAwQUAAgACAANlmRCAAAAAAAAAAAA AAAAGwAQAHJlZ2lvbi1iYWNrZ3JvdW5kLWNsaXAuaHRtbFVYDAB80DRRWdA0UfUBFACVVG1v0zAQ /pz+iiMICSSylG0dI00rZVs7uhemvg3KNye+JmZOHNnOsg7x33GSZhsDCciXsx/fPc9d7mz/BRWR 3uQIiU75sONXBjjJ4oGNmV0BSOiwY/kpagJRQqRCPbCXi7FzaFe4ZprjcIYxExmEJLqJpSgyChFn ue82p8ZN6U29yOF7x7JSImOWedDtd6wfnY61o0vhUKFVffrI4kEh+WubEk08lpIY3TyL+yFReLD/ ll0fXc3K7vlpLALzfZovk9EyNqvjahvEx8HKmKN7zGS3AmYjPppez/Z3i72FmnaDSVCeTFcfgtLt najg9CKh09l4tfwmFu4ZDQ/O+CXB5Ry/7O6N5VEwGumPh0fxmF4wKT/vf1hNgjgRbmlYxtHVyTxN CtxbfO0ta/H58vpqdt47Xk0mA/sNZMKRmCPR23pfRiLTmGnIq3rXZuOsScr4xoMgwbTfgordowe7 3fyugjjL0EmQxYn24F3j5pQY3jATzkXpsEwLD9atSE5kpVFJlIzqxAS931I9sLRA25GGtg6XTU+f hveeh7dAKCRF6UhCWaE86HVfPaLGzXiBEpxRCLlpbv+XJjuR4MJ4bZCbIn4rai1F2hRliVuUFeZB wijFrM7UeqjUSyqHZyPUsvMq41hiG+W725H03WbE/VDQTTWqwtwDy/I5G14aPtiIQkIqCoVQ0+sE oeYBM7AQoslnBxYGbPKHiMmII6hEFNzUi0CZyjnZIAXzN0mTyJbhMc0d3zWCf9OVhuRfVJVmnP+3 tu/WpfuU3QKjA3s7pHadVj68M58fyj9bN68JTOhThqYvtnkMiFIDu73lDWPr1MxZg7UEjfXdpiem RdXr9BNQSwcIlGhhWX8CAACtBAAAUEsBAhUDFAAIAAgAE5ZkQqzBzNJsAgAAbAQAACQADAAAAAAA AAAAQKSBAAAAAHJlZ2lvbi1iYWNrZ3JvdW5kLWNsaXAtZXhwZWN0ZWQuaHRtbFVYCAB60DRRZdA0 UVBLAQIVAxQACAAIAA2WZEKUaGFZfwIAAK0EAAAbAAwAAAAAAAAAAECkgc4CAAByZWdpb24tYmFj a2dyb3VuZC1jbGlwLmh0bWxVWAgAfNA0UVnQNFFQSwUGAAAAAAIAAgCzAAAApgUAAAAA
