core/utils.js resolved the icon fallback with a templated
import(`bootstrap-icons/icons/${name}`), which webpack turned into a lazy
context over all 2078 icons: ~65KB of filename→chunkid map inside the eager
patterns chunk, ~60KB of the chunk→hash runtime map in bundle.min.js, and
~2000 tiny chunk files in dist — parsed on every page for a fallback that is
almost never hit.
Resolve the fallback by fetching the icon resource URL from iconmap.json
instead (Plone already serves every bootstrap icon as a static resource),
keeping the same return shape (SVG markup string) for callers. Removes the
icon context entirely: the dist chunk count drops from ~3578 to ~1469 files
and bundle.min.js shrinks by ~80KB.
… of Plone Without a portal URL the fallback requested /++plone++bootstrap-icons/..., which only Plone serves, so standalone and CDN integrations got empty icons. Copy the bootstrap-icons SVGs next to the bundle and fetch them from webpack's public path in that case. The markspeciallinks tests failed because jsdom has no fetch; they now stub it to serve the icon files.

Summary
resolveIcon's fallback used a templatedimport("bootstrap-icons/icons/…"), which webpack turns into a lazy context over all 2078 icons, with its filename→chunk maps in the eager JS. The fallback now fetches a static SVG:webpack.config.jscopies the bootstrap-icons SVGs todist/bootstrap-icons/(copy-webpack-plugin), so standalone/CDN integrations and the demo keep working.Evidence
