Thanks for contacting Syncfusion support.
We have already fixed the reported issue and it is available from the Syncfusion version v17.2.49. Since the root issue is in Angular cli, they have fixed the issue in the version 8.3.1. So please update both Syncfusion and Angular packages to overcome the reported issue and refer to the below documentation link for updating the Syncfusion package.
