Problem with TMSFNCBitmapContainer

Hello,

if I try to add a SVG image(s) to an TMSFNCBitmapContainer no image is displayed on screen in the editor and nothing is painted during runtime.

If I try your example FNCUITreeView everything works finebut I try to use it in a VCL app.

What could I do possibly wrong?
The svg is from icon8 and has a fixed size

<svg xmlns="http://www.w3.org/2000/svg"  viewBox="0 0 48 48" width="50px" height="50px">....

Besides this there seems to be a theming bug in the editor of TMSFNCBitmapContainer. The buttons have a black text in the dark theme of the ide.

Do you have other third-party components installed or units in the uses list that might override the type of class we use for registering SVG? If you are using Skia, this can be a cause, also if you have installed TMS VCL UI Pack, the SVG class is registered. Please add VCL.TMSFNCTypes / AdvTypes to the uses list and see if that helps for runtime SVG editing.
