When using the libertine
package with newtxmath
, the spacing after an italic "f" looks too small if a math character follows. Is there solution for this, apart from fixing all such occurrences manually?

\begin{theorem}
The spacing of $G$ and the preceding of is off.
Similarly for ``of $\mathsf{i}$''.
