Obtaining size of a billboard

Is there any way to obtain size of a billboard (width and height)?
I need this for example when a user picks a billboard, so that I overlay some HTML stuff on top of it.

I checked the documentation,and also inspect the property of some billboards at run time

Width, height and image properties exist, but they all come as undefined (I understand that width and height are optional)

So, is there any way to obtain the width and height if the billboards were not created with a specific dimensions?

Currently, this information is buried inside implementation details (texture coordinates inside the texture atlas).

I’ve opened a pull request to fill in the width and height values after a billboard is loaded.
