There seems to be an issue with the core library when using DayPilot Scheduler for Angular (see attached image).
> The error appears in the console when right-clicking on any link between events
> The context menu appears fine and callbacks do get executed
> Found first in a live app, then confirmed in a sample app from DayPilot's documentation
> The context menu does not appear in our live app due to the error and custom error handlers, which makes this issue more problematic
> DayPilot Pro 2021.3.5055
As a temporary fix we have found that removing the onMouseUp event listener from the link element prevents the error from being thrown, but that is definitely not the best way to deal with the problem.
Any support with the issue is appreciated, thanks!
