In 4.5 the Popup's featureMenu doesn't render svg or base64 encoded images, however in 4.4 both these rendered as expected.
I'm injecting some icons into the popup's title and it renders correctly in the title but not the featureMenu. Is there a way to get this working again or is this behavior now by design?
I've attached a couple images to show what I'm seeing. This behavior is exhibited in Chrome, IE, Edge, and Safari across both macOS and Windows.
Image rendered correctly in the title
Img not rendered in featureMenu
Thanks for any ideas you may have.
