A workaround to display icons for top-level menu items?

So a issue I ran into very quickly with the built-in menu component is that the Icon doesn't get displayed at all for the top level item, such as described and discussed in this github issue:

https://github.com/AvaloniaUI/Avalonia/issues/8865

I am just wondering, as a complete newbie to Avalonia coming from WinForms, is there a way I can somehow override the rendering of the element itself to fix this myself?
