Kalbaliev opened a new issue, #1276: URL: https://github.com/apache/airflow-site/issues/1276
**Summary:** Tag filtering in Airflow Web UI breaks when the tag name contains an ampersand **(&)** character. **Affected version:** Observed in `Apache Airflow 3.1.2` (released 2025-11-05) **Detailed description:** I have a DAG with a tag named Corporate & SME. This tag appears correctly in the tags dropdown list. **However, when I click on this tag in the DAG list, only “Corporate” appears as the selected tag, and the filter returns no results.** When I test with Corporate-SME, everything works as expected. **Possible root cause:** The & character is not properly URL-encoded in the link. Expected behavior would be a URL like: `/dags?tags=Corporate+%26+SME` But instead, the generated URL is: `/dags?tags=Corporate%20&%20SME` **Expected behavior:** When clicking a tag containing an ampersand, the URL should be properly encoded, and the filter should correctly apply to the full tag `(Corporate & SME).` **Actual behavior:** The ampersand breaks the query parameter, resulting in only part of the tag being recognized `(Corporate)` and no DAGs being returned. **Picture 1.1 & 1.2: When click to tag name on both view** **1.1** <img width="1728" height="383" alt="Image" src="https://github.com/user-attachments/assets/c04be67a-35fb-4fd6-9ab5-97bc3c18c648"; /> **1.2** <img width="1728" height="380" alt="Image" src="https://github.com/user-attachments/assets/a5acd591-a796-466a-867f-f0d0c38c2b14"; /> **Picture 2** <img width="1728" height="952" alt="Image" src="https://github.com/user-attachments/assets/1a9aae94-6e67-4ff0-8c81-f39d56fbc7d4"; /> **Picture 3** <img width="1726" height="191" alt="Image" src="https://github.com/user-attachments/assets/e84f5ee2-3b55-4a04-abf3-b547a374209f"; /> **Picture 4** <img width="1728" height="952" alt="Image" src="https://github.com/user-attachments/assets/8bd5abcd-00f3-4eb4-8cd9-35cf625954df"; /> -- This is an automated message from the Apache Git Service.
