Is it possible to set crossorigin="anonymous" for dynamically-fetched scripts?

[keeganwatkins]

Given the following architecture:

• Application hosted at https://a.com
• Frontend assets bundled with Parcel (v2.x), served from a CDN at https://b.com

...CORS behavior limits error-tracking unless crossorigin="anonymous" is set on the <script /> elements for the assets served from https://b.com (docs).

Setting crossorigin="anonymous" on the entry scripts is easy as we're in control of the markup, but I'm wondering if it's possible to set crossorigin="anonymous" on the <script /> elements for dynamically-loaded chunks, e.g. anything that is behind a code-split point and loaded via dynamic import( ... )? I found this bit of relevant script-loading code, but it's not clear to me how we'd alter/extend it globally.

As an example of what I'm hoping is possible, see the output.crossOriginLoading option in Webpack.

Any help would be appreciated!
