Using RemNote in the Vivaldi Browser Web Panels

Is anyone using the Vivaldi Browser?

Does your RemNote work well in a Vivaldi Web Panel?

I use Web Panels all the time, I love them, but they don’t seem to work with RemNote!

When I first open it, I can type plain text ok, but I can’t make links or use any other RemNote functionality. And then if I push it, by trying a few things to make it work, then the Web Panel even stops letting me type plain text…

I really enjoy the Web Panel functionality of Vivaldi, and I’m super keen to get it working somehow - does anyone know anything about this?
