Comment (by wuthrich):
Oh, there is a lot to do, I discovered.
The #20244 will be independent as I will call extension directly rather
than {{{root_field}}}.
The main issue is the normalisation for p-adic L-function involving
negative modular symbols. They are used when a quadratic twist is used and
that happens even for {{{E.sha().an_padic(p)}}}. I am close to resolving
this.
The major outstanding issue that I will not change here is #4656 which
makes some coefficients (with negative precision sometimes) disappear from
the series.
