Indeed, another annoyance I have with Designer is how not purely vector it is. I mean it's great and makes it a breeze to make documents but it really sucks for making web-targeted SVGs. Both Inkscape and Illustrator support using SVG as the project file and I never have to guess if the feature I'm using is going to actually export as vector or just rasterized and embedded as a base64 PNG (which is true for fancy gradients and some of the more advanced masking, not even just the raster persona stuff).
