Why is there SVG flags wich the content is just a filename?

[foxypiratecove37350]

There is some SVG waved flags which the content is just a filename, like the file emoji_u1f1e7_1f1fb.svg:

emoji_u1f1f3_1f1f4.svg

I know this is for flags aliases but it just don't work and do this error during the build for COLRv1 (exemple with the file emoji_u1f1e8_1f1f5.svg:

FAILED: picosvg/clipped/emoji_u1f1e8_1f1f5.svg

I think those are symbolic links.

I think those are symbolic links.

Me, I think those are suposed to be symbolic links but it's just the filename in the SVG file. On my local clone of the repo I've just replaced those by the content of the file with this filename.
