[ShaMan123]

I think we should consider making FabricObjectSVGExportMixin a mixer function like collection and drop applyMixins

I need this merged

[ShaMan123]

All of there belong to canvas along with drawControls and _applyCanvasStyle

[asturur]

So how this passed before withtout the ts-nocheck on top?
How did i get a clea build without those types?
