[5.2.1.p1] Event Trigger alters they way buttons behave

Not sure if it’s 5.2 specific problem but when you have a game object with Event Trigger component and Buttons added as its children game objects, the way buttons are clicked is altered.

Normally, you can still move your mouse a bit while clicking to successfully click a button but if a button’s parent has event trigger component, you no longer have this “margin” thus lowering usability of UIs.

I have reproduced and confirmed this bug in a new project. I hope it gets fixed

This is because the EventTrigger is a very heavy component and can override or interfere any other objects using the event interfaces.
You should not use the EventTrigger component if you can help it, you should have scripts that properly implement the event interfaces and don’t implement duplicate interfaces on the same GO’s
