Is this necessary? For alphaEnabled, requesting alphaEnabled:true does not
guarantee an alpha enabled window, so the window is expected to check what it
got. For IME, I think we either guarantee an IME window, or fail to create the
window, so the extension wouldn't need to check this.

I thought that IME extensions can create non-ime window. But since you and ben
both dont like the idea, I have changed the code so that IME extensions can only
create IME window. In that case, this is not necessary. Removed.
