Can't show HTML + SVG

I used to use JEditorPane, but it can only display HTML, cannot display SVG, and nested SVG HTML cannot complete display.

Then I use JSVGCanvas, but it can only display SVG, cannot display HTML.

Is there any way to solve this problem?

Configure JEditorPane to use the JSVGCanvas canvas for SVG. To achieve that, you need a specialist HTMLEditorKit. Here is the HTLMEditorKit of Appleteer.
