Content & configuration

Example Swagger/OpenAPI definition:
Petstore example, or anything else, does not matter to the subject of this issue.

Swagger-Editor configuration options:
No editor configuration possible through Docker deployment.

Docker command:

sudo docker run --rm -p 8080:8080 swaggerapi/swagger-editor:next-v5-unprivileged

Describe the bug you're encountering

As said in the title, the local storage does not store the editor content, gets overwritten with {} on every load.

To reproduce...

Steps to reproduce the behavior:

1. Start an editor instance with Docker
2. Open the editor
3. Edit anything, or load an example
4. Close the tab
5. Open the editor
6. The editor content is erased.

Expected behavior

Editor content is persisted with local storage.

Screenshots

demonstration video

The video is recorded on an instance hosted behind a reverse proxy, however this does not effects the issue, as the behavior remains the same with a locally ran instance started by docker run.
