ChromeClientImpl.cpp has a variable, m_ignoreNextSetCursor, which was used to prevent a WebKit-triggered call to setCursor from overriding what the plugin does. In bug 35132 that call was removed, so now the workaround is not necessary, and is actually preventing windowless plugins from setting cursors (since all the calls are now coming from the plugin, so it's constantly being set to true).
