The patch fixes the background-color issue, however the same problem occurs with setting the text color for a div.  I've added a reproduction case which demonstrations the problem (TextColorBug.html).

Does this bug still apply in Safari 9?
Comment 10 Yuki Sekiguchi 2016-01-31 21:19:59 PST
I checked Demonstrates Bug and confirmed that it wasn't reproducible on Safari 9.0.3. However, Bug 119524 remains.
