Comment (by pbruin):
This guess is corroborated by the fact that the following change also
appears to fix the bug:
{{{
#!diff
--- a/src/sage/rings/finite_rings/element_pari_ffelt.pyx
+++ b/src/sage/rings/finite_rings/element_pari_ffelt.pyx
@@ -202,7 +202,7 @@ cdef class
FiniteFieldElement_pari_ffelt(FinitePolyExtElement):

if isinstance(x, FiniteFieldElement_pari_ffelt):

(<FiniteFieldElement_pari_ffelt>x)._parent:
+ if self._parent ==
(<FiniteFieldElement_pari_ffelt>x)._parent:
pari_catch_sig_on()
self.construct((<FiniteFieldElement_pari_ffelt>x).val)
else:
}}}
After #16855, this change effectively does nothing.
