Yew is setting parameters too late

[Roba1993]

I have a strange behavior. I use the sap ui5 web components and render an icon with their <ui5-icon name='home'> component.
The problem is, that I always get an warning from this function.

It seems like, that yew is creating and rendering the base element first and then add the parameters (name in this case) in a second step. Is there a way to circumvent this?
