Hi,
I don’t think it takes even milliseconds, as the font file size is 2.3kb only, without gzip, with gzipped communications it’s even less. I’m not even sure it is possible to move this asset to a link tag with a preload attribute, as WordPress does not have an option to add the ‘preload’ attribute there.
I did a quick test on gtmetrix with a 60kb icon file, it took 12.2ms, so 2.3kb should take much less time to request, even less if you use cloudflare or any other CDN.
