Why does file-type's fileTypeFromBuffer return different outputs for SVG files?

[anumysore5]

I am aware that the file-type README says that it doesn't support SVG files. Based on this, I would expect that any SVG file input to fileTypeFromBuffer would return undefined. But I am seeing some inconsistent behavior for different SVG file inputs.

For example, the output for this SVG file is undefined as expected. However for this SVG file, fileTypeFromBuffer returns { ext: "xml", mime: "application/xml" }

Could you please let me know why there is such discrepancy in the outputs?

SVG is XML. That is as far file-type goes.
