[Tagging] Rio de la Plata edit war

[Joseph Eisenberg]

Ok, I checked the changeset: https://www.openstreetmap.org/changeset/79201390

I doesn't look like the user who did the revert of the change was
intending to edit-war, but was instead responding to the appearance of
the Rio de la Plata being rendered as land on some map styles.

This always happens for the first few hours up to a couple days after
a change to the coastline, because the ocean shapefiles used to render
the marine water environment are only updated once a day at most (and
if the coastline is broken it will not update every day).

I responded to the changeset to explain this.

Keeping the river area while also moving the coastline will prevent
this visual bug from occuring.
