|Flash clipping||OK||Flash on Linux is OK. Flash on Windows often doesn't respect the iframe. If you hide and then expose the window, the shim does seem to have an effect on display, though you can't select the HTML text. Other types of plugins respect the shim though. Is Flash doing something peculiar?||OK|
|equal z-index||iframe at same z-index always clips plugin, regardless of creation/document order.||Ignored; see above.||iframe at same z-index always clips plugin, regardless of creation/document order.|
|Order that iframes appear in document.||Irrelevant.||Inline iframes are apparently always behind plugins. To clip a plugin, you have to dynamically create the iframe after the plugin is created.||Irrelevant.|
|Page scrolling||Visual layering breaks when scrolling the page, until someone triggers a repaint.||OK||OK|
|visibility:hidden and display:none||iframe disappears and no longer clips plugin|
|opacity||The iframe clips the plugin as usual. The iframe blends with whatever is behind the plugin, as if the plugin were not there.|
