    url: "openapi",
    dom_id: "#api-explorer",

Describe the bug you’re encountering

When opening a path that is in a tag “group”, it disappears and then reappears underneath the default tag.

This is a regression in 3.30.1; I temporarily set my unpkg URL to 3.30.0 (https://unpkg.com/swagger-ui-dist@3.30.0/swagger-ui-bundle.js) and the behavior no longer happens. I set it back to 3 to get the latest version and it started happening again.

To reproduce…

Steps to reproduce the behavior:

1. Go to a path in a tag “group”
2. Click on the path item
3. See error: the path item will disappear and reappear further down the page under a new default tag group.
4. The path item under the default tag will sit and spin.

Expected behavior

The path item should open in place.

New release to resolve this issue, v3.30.2

@tim-lai, jsDelivr appears to still be serving 3.30.1 for version 3. Is this going to update automatically or does it require action on Swagger’s part?
