As designed image/oembed cache uses same filesystem as internal_data

[Xon]

Affected version

2.1.0 Patch 2

When redirecting internal_data, it also redirecting the image/oembed cache folders may not be desirable as these folders are populated on view rather than during content creation or a admin triggered option.

TBH, this is really just expected -- if you redirect internal_data, you redirect everything that is saved via that endpoint.

If you want to do something more nuanced for your needs, you may need to make a Flysystem adapter that redirects the target based on the top-level directory, for example.
