Local Setup for html5-qrcode.min.js automatically runs throug UI

[managedata]

Hello,
when I use <script src="https://unpkg.com/html5-qrcode@2.0.9/dist/html5-qrcode.min.js"></script> all works like expected.
The UI appears, I can select a camera, scan and the QR code is recognized.

When I use my local copy ./node_modules/html5-qrcode-2.3.4/minified/html5-qrcode.min.js"> the UI appears,
then the application runs automatically through all steps. All input activites are done by the app automatically.

Any idea, what I am doing wrong?

BTW: html5-qrcode is a very good solution.

Greetings

Herbert
