Found in Version 25.0.1335.0 canary 1. Open the attached file in a browser Result: The overflow text is hidden but should be visible as it should inherit the default value of overflow-x and overflow-y. The computedStyle shows as visible. Comment out the border-radius on region-3 and the overflow text will again be visible. Just as a control, I tested this scenario without regions with just a div + border-radius and the default overflow behavior is correct in that scenario

It looks like it will just not paint the overflow at all.
Created attachment 188929 [details] Patch The fix for https://bugs.webkit.org/show_bug.cgi?id=74132 also fixed this bug. I still think it deserves a test.
