Corrupted WOFF2 file upon upload

Sorry to post this here, but I would like to file a bug in the admin area of Shopify - the issue is ignored in the community support forum and support can't or won't file a bug report on my behalf.

When uploading a WOFF2 font file to the 'assets' folder of a theme the file is corrupted. In my case the file size changes from 21KB to 39KB when served via asset_url

The browser console logs the following errors and the font fails to load.

Failed to decode downloaded font
OTS parsing error: Failed to convert WOFF 2.0 font to SFNT

When uploading the file to 'Content' > 'Files' and loading the file via file_url in the CSS, the font load correctly. ( So it's not a corrupt font file before uploading ).

Other customers experiencing the same.

Please advise on the correct channel to report bugs - as support is always a brick wall.

The report concerns WOFF2 uploads in Shopify's admin area, comparing the asset_url path with the working file_url path. No repository file, test, or entry point is identified, so first confirm whether this behavior belongs in Liquid; done would require a reproducible in-scope failure and a test showing the uploaded font is served without corruption.
