Mixpanel Element Click Event Not Capturing Consistently: Bug or Feature?

Hi everyone! To track user actions (such as clicking a button on my website), I’ve used the autocapture event “Element Click.” I’ve also added an ID attribute to the button to help identify it. However, when users click the button, Mixpanel doesn’t always capture the event correctly. Some of the captured events include the element_id in the properties, while others don’t. I’m wondering if this is a bug or expected behavior?
