Comment (by gziolo):

 As far as I can tell we should be able to use one of the unminified files:
 - https://unpkg.com/browse/element-closest@3.0.2/index.js (Common JS)
 - https://unpkg.com/browse/element-closest@3.0.2/index.mjs (ESM)

 So we should need to update references in both `vendors` and
 `minifiedVendors`.
