I can agree that the logic can be a bit confusing. It is kept for backward compatibility and of course if we find a way to change it without affecting other functionality that depend on it, we will do that.
If you don't want to use a timeout in your calculations, I would suggest to check the approach used in the attached file. There we are using Telerik's static client library
for getting the needed size and position.
All the best,
the Telerik team
