### Bug description We have updated our installation from 4.0.2 to 4.1.2 today. All the Handlebars charts that use `formatDate` helper started throwing `i is not a function` error. Steps to reproduce: 1. Create a new dataset with one value. ```SQL select '2025-04-01'::timestamp as t ``` 2. Create a new Handlebars chart from this dataset. 3. Add `t` column to the columns list and hit "Create chart" button. The chart renders normally. <img width="1056" alt="Image" src="https://github.com/user-attachments/assets/553445fe-5c9b-41ce-bb2b-05403b18037a"; /> 4. Modify template as follows: ```HTML <ul class="data-list"> {{#each-data}} <li>{{formatDate 'DD.MM.YYYY' t}}</li> {{/each}} </ul> ``` 5. Now the chart preview renders the error. <img width="1046" alt="Image" src="https://github.com/user-attachments/assets/0a5395ce-02f4-4300-bce5-5e8d454fa721"; /> ### Screenshots/recordings _No response_ ### Superset version 4.1.2 ### Python version 3.11 ### Node version I don't know ### Browser Chrome ### Additional context There are no related errors present either in the browser console or server logs. ### Checklist - [x] I have searched Superset docs and Slack and didn't find a solution to my problem. - [x] I have searched the GitHub issue tracker and didn't find a similar bug report. - [x] I have checked Superset's logs for errors and if I found a relevant Python stacktrace, I included it here as text in the "additional context" section. -- This is an automated message from the Apache Git Service.
