Comment (by wuthrich):
I changed my mind about the first problem. There is no meaning to a local
version of reduced equation. So in order not to break anything, I propose
to reduce the local minimal equation only if it is globally integral
coefficients.
The attached patch was exported from 5.9 after having applied
the patched for #12509 #13953 #11630 in that order. It solves the two
above issues.
