Potential issue of incorrect logic in the waitForElement util

[NoamAnisfeld]

On src/utils.js the util function waitForElement observes a given target node in order to catch a certain element once it's being added to the target node.

However, when it actually looks for the existence of said element it uses document.querySelector rather than target.querySelector. This occurs twice - on the precheck before observing and in the observer callback.

This may lead to a bug when an element which isn't a child of the target node would be incorrectly returned.

Thank you!

You're right. And if you're going to fix it, I think the target needs to be document if it isn't provided.
