What is actually happening?

It is a string

This problem is mainly caused by the fact that when I define a test case, I assign a property value through EL and discover that the assignment is wrong. If I do not assign a value through setAttribute first, the value will never be a number, And I think there are scenarios for assigning values through the JS API.
