🐛 Bug: SVG logo breaks png preview generation (easily reproducible)

[KemingHe]

Bug

When using custom SVG logo for preview, the logo disappears when downloading in PNG format. The logo shows up fine if using URL to dynamically render the preview.

To Reproduce

1. Go to https://socialify.git.ci/wei/socialify/image?logo=https%3A%2F%2Fraw.githubusercontent.com%2Fwei%2Fsocialify%2F1f520b6bfe799300bcff9edcdc330828d681d382%2Fapp%2Ficon.svg&name=1&theme=Light
2. Click URL and paste into a new tab/window to view the working preview (with logo).
3. Click DOWNLOAD and select the .png option to view the bugged preview (missing logo).

SVG logo used

https://raw.githubusercontent.com/wei/socialify/1f520b6bfe799300bcff9edcdc330828d681d382/app/icon.svg

Image url (dynamically rendered) with correct logo

Downloaded png file with bugged (missing) logo

JPEG (and webp) works fine

Speculation

This might have something to do with only how PNGs are generated.

Thanks for the detailed repro. Likely something we can take care of when upgrading satori #449

It seems to work for other svgs, e.g.: https://socialify.git.ci/wei/socialify?logo=https%3A%2F%2Fgist.githubusercontent.com%2Fwei%2F13e3f6e161cb1d0709abd847102dc80c%2Fraw%2Fmlh-color-square.svg&name=1&theme=Light

Better reproduced and isolated in #488, closing as duplicate.
