new snafu with Branding > Admin Bar > Parent Menu > Entry Title > image

the image doesn't show on subsites... it shows on mainsite and network admin, but 'sometimes' the image is super tiny on the main site in chrome... not exactly sure when this started, but I think it was working after WP3.9 update (not 100% sure) -

something is resizing the image not sure what, but maybe normal

anybody else see this? any ideas?
