[Jontes-Tech]

Describe the bug
A clear and concise description of what the bug is.
In chromium, http://localhost:8080/ipfs/cid redirects to https://cid.ipfs.localhost:8080. Kubo's gateway only serves HTTP, not HTTPS.

To Reproduce
Steps to reproduce the behavior:

1. Create an HTML (over HTTP) file.
2. Create an <img> pointing to https://ipfs.io/ipfs/any-cid-here
3. Image will fail to load because it tries to redirect to https on 8080.

Expected behavior
A clear and concise description of what you expected to happen.
Image loads successfully

@Jontes-Tech I was unable to reproduce in fresh install on Chrome 126.0.6478.36

• Opening http://localhost:3000/ipfs/cid does not redirect to https://cid.ipfs.localhost:8080.
• Bit confused what steps (1) and (2) mean – mind rephrasing? Looks like you've cut some important text.

Yeah, sorry. Github stripped away my HTML tags. I've edited the message to make it clearer.

Basically http://localhost:8080/ipfs/cid should redirect to http://cid.ipfs.localhost:8080 but instead redirects to https://cid.ipfs.localhost:8080 when served as an image in an HTTPS context.

One example of this is present on the following webpage: https://ens.page/jontes.eth

You will see in the network tab how IPFS companion redirects to https:// on localhost.

See the screenshots I've attached:

Reproducible on both Chrome and Chromium, 125.0.6422.141 (Official Build) Arch Linux (64-bit)
