[NTG-context] Placing number in \sqrt

Hello, compare placing "3" in the following examples: ---- \starttext $\sqrt[3]{5}$ % (1) \par $\sqrt[3~]{5}$ % (2) \stoptext ---- In the first case, the "3" is placed naturally by ConTeXt and placed more in the centre of "V" part of the square sign. In the second example, the "3" is shifted manually by adding "~" and the final placement seems to me a bit better. What is your opinion - is the case (1) OK/intended and user should avoid any manual shifting? Or manual shifting is OK? Or is there a way to affect this placement globally in ConTeXt, e.g. setting an internal variable? Best regards, Lukas
