Plane-15 glyphs not rendered.

[RixInGithub]

hello everyone who is reading,

i tried to make an icon which starts in the pua-a plane 15 character U+F7676. but as you can see here, my browser (chrome) refuses to render it. fontdrop shows the glyph, but the unicode key is 7676. i tried U+7676, U+F7676, nothing worked. then out of curiosity i tried plain U+E000. that worked. pls fix cuz i want to make icons in U+F7676. i tried disabling ttf and using woff instead, didnt work either.

hilaricons.ttf.zip

void({generateFonts,FontAssetType}=require("fantasticon"))

async function makeHilaricons() {
	console.log(await generateFonts({
		name: "hilaricons",
		inputDir: "./hicns",
		outputDir: "./dist",
		fontTypes: [FontAssetType.TTF, FontAssetType.WOFF],
		assetTypes: [],
		codepoints: {
			f7676: 0xf7676
		},
		normalize: true
	}))
}

makeHilaricons()

i tried changin normalize to false but that also didnt work. im on windows and i had to apply this for fantasticon to work. i guess ill be using smth else.
