I am not sure this is a bug. There is now a minimum height required to dock, and your window size might be below that minimum.

If I hit the dock button twice, it does dock, so the height is not the issue here, the issue is with the initial loading of the inspector. It is a bug, it should dock. Also, 1024x768 docks on the Mac.

It appears to be the same as https://bugs.webkit.org/show_bug.cgi?id=36166 where preferences are not synced with file storage for some reason.

Then why does it draw the docked icons? If the preferences were not stored, then I would think it would draw the normal undocked icons. Additionally, starting out attached is the default, so I would think that if the preferences weren't synced, then it would try to attach anyways.

I debugged this a little bit, and noticed canAttach is being called twice, the second time it is being called from showWindowWithoutNotifications, and the window height of the inspected page made it seem like the inspector was already attached, therefore canAttach returned false, causing this behavior. I don't think this has anything to do with CFPreferences.

WebKit/win/WebCoreSupport/WebInspectorClient.cpp:364
 +          if (shouldAttach && !canAttachWindow())
This check could be done early.

Will this patch be committed soon? It would be really helpful for Apple to have this fix in. Is it ok if I commit it, or at least mark it commit-queue+?
