When an element is defined in a stencil XML file but not declared in the corresponding JS shape file, it causes redundant loading of the JS file even when using minified bundles.

Describe the bug
When an element is defined in a stencil XML file but not declared in the corresponding JS shape file, it causes redundant loading of the JS file even when using minified bundles. Specifically:

• mxgraph.aws4.folder exists in src/main/webapp/stencils/aws4.xml
• No corresponding declaration exists in src/main/webapp/shapes/mxAWS4.js
• Minified bundles shapes-14-6-5.min.js and stencils.min.js are loaded
• Browser network tab shows redundant request to /drawio-viewer/mxAWS4.js

To Reproduce
Steps to reproduce the behavior:
（see the attachment file :

re_request_mxAWS4.js.html

）

1. Create diagram with mxgraph.aws4.folder element
2. Load minified bundles: viewer.min.js, shapes-14-6-5.min.js, stencils.min.js
3. Monitor network requests in browser dev tools
4. Observe failed request to mxAWS4.js (404 error)

Expected behavior
When using the minified bundles viewer.min.js, shapes-14-6-5.min.js, and stencils.min.js to render diagrams:
Shape definitions already included in shapes-14-6-5.min.js (e.g., AWS4 shapes) should not trigger separate requests for their original source files (e.g., mxAWS4.js).

Additional context
Add any other context about the problem here.

Start with src/main/webapp/stencils/aws4.xml and src/main/webapp/shapes/mxAWS4.js, then reproduce the diagram using viewer.min.js, shapes-14-6-5.min.js, and stencils.min.js while monitoring the browser network tab. Confirm that mxgraph.aws4.folder is covered by the minified bundles without a separate mxAWS4.js request or 404.
