Kerning/Alternate Shape Problem "f within angle brackets" ⟨f⟩

[Kybernator]

Describe the bug
An f within angle brackets (as used in linguistics for graphemes) collides with the closing bracket.

Steps to reproduce
type ⟨f⟩ in Libertinus Serif, be it regular, italic, bold or bold italic

Additional context
It would probably yield a considerably better result if the f would show the contextual alternative (narrower version), added kerning might still be necessary.
