[Bug] The SVGs in /build/svg/ don't have the `octicon` classes attached

[fregante]

Describe the bug

The classes:

• ✅ show up in the SVG generated by toSVG(): https://github.com/primer/octicons/tree/main/lib/octicons_node#class
• ✅ show up in the React components (line 65) https://www.unpkg.com/browse/@primer/octicons-react@19.8.0/dist/index.esm.js
• ❌ but they don't appear in the static SVGs: https://www.unpkg.com/@primer/octicons@19.8.0/build/svg/alert-16.svg

Expected behavior

Could you include the octicon octicon-something classes in the built SVGs?

I only need this in @primer/octicons, but the issue also appears in @primer/octicons-react (however I don't understand the point of the built SVG files in that package since they're not allowed by the exports map)

Context

I want to import the raw SVGs in my extensions

• refined-github/refined-github#6878
• refined-github/refined-github#7152

So this is because the icons are plainly copied from the ./icons folder, which understandably doesn't have any extraneous attributes.

This issue doesn't affect me anymore though, I'm using https://github.com/fregante/octicons-plain-react
