Created attachment 97800 [details] Test-Case We have build a simple test-case to reproduce this issue. Seems like its a regression because this problem does not exists in Chrome stable but in Chrome beta and all newer versions. Also the Webkit nightly from today had this issue. Brief description of what we do: We are adding a DIV element to the DOM dynamically and setting a CSS background image. After a second, we remove the element from the DOM and again a second later, we change the background image's value and add it back to the DOM. Unfortunately, the old value is still present. Adding the DIV to the DOM before we change the background image works as expected.
