Description

This issue was raised on the Applicaiton Insights repo, but we don't define "__name" and according to the people consuming us when they roll back to v20.2 the problem does not occur

Uncaught TypeError: Cannot redefine property: name
at defineProperty ()
at __name (chunk-TJFVSI2U.js:20:33)
at AnalyticsPlugin.js:57:10

microsoft/ApplicationInsights-JS#2643

Based on out analysis thus far this is a bundling / packaging issue that has been introduced in Angular 20.3 and not a specific issue for Application Insights.
