Hi together,

we have updated our dependencies and encountered an issue after upgrading the Onyx Version from 1.0.0-beta.100 to 1.0.0-beta.123.

On all input form elements, we get the console warning, that the value is read-only (see screenshot at the end).
The components work as usual, but it blows our console.

The issue was introduced with the version: 1.0.0-beta.108 (c7c3296: feat: Expose input elements of form elements)

Current package setup:

• "sit-onyx": "1.0.0-beta.108",
• "@sit-onyx/icons": "1.0.0-beta.6",
• "@sit-onyx/storybook-utils": "1.0.0-beta.75",

Vue Version: 3.5.11

No peer-dependency issues.

Hope you can help out quickly :-)

Best regards and a big thank you for your awesome work!
