The following MWE procudes this result:

[![eq](https://i.stack.imgur.com/gCGPc.png)](https://i.stack.imgur.com/gCGPc.png)

As you see, I want to have tiny equation numbers/tags, but currently it is not centered vertically of course (as the rule shows), it lies on the baseline. How can I possibly change this? That is, I want to print (1) a bit higher.

(NB: I do *not* want to change the formatting of `\ref, \eqref, \cref` though).

Thanks for your ideas!

\begin{equation}\label{fun_eq}
x^2+y^2+z^2 + x^2+y^2+z^2 + x^2+y^2+z^2 =
3(x^2+y^2+z^2)

My favorite equation is \ref{fun_eq}, \eqref{fun_eq}, \cref{fun_eq}
