The old Paperclip configuration was very clever and easy to use but it
was also a complicated implementation building on the complicated Spree
preference system.
I simplified this with Active Storage, storing simple references to blob
ids and default URLs as backup.
So I think the issue is that all the HTML is wrapped on an
`off-canvas-wrap` class that is used for doing the sidebar car open over
main content. The problem is that when this car sidebar is open body of
HTML overflow is changed to `overflow: hidden` and search bar use CSS
`position: sticky;` which doesn't work when its parent has overflow
hidden. The issue was that `off-canvas-wrap` had an `overflow: inherit`
which means when body is set to overflow hidden this div inherits it and
break search bar position sticky when cart sidebar is opened. The
solution is to use `position: initial` which means use what a div has as
default value for `overflow` which I think it's `visible`. This class is
overriding the same class that comes from Foundation Framework that set
this div to be `overflow: hidden`. The override was added when [we added
search sticky](ff69389bb0)
More info about the problem with [position:sticky and its parent having
overflow hidden](https://css-tricks.com/dealing-with-overflow-and-position-sticky/) also info about [position initial vs inherit](https://stackoverflow.com/a/29661356)
Ensures the non-fingerprinted version of the favicon will be used directly from `/public/favicon.ico`. Needed after recent changes to the Rails asset pipeline.
The map is displayed using https://leafletjs.com/
To enable Open Street Map go to the Admin -> Configuration -> Content section and click 'Open Street Map Enabled'.
The 'Open Street Map Provider Name' setting can be used to configure different tile providers thanks to the Leaflet-providers extension (https://github.com/leaflet-extras/leaflet-providers)
Some tile providers require an API key, this can provided in JSON format e.g. '{ apiKey: 123 }' in the 'Open Street Map Provider Options' setting.
Each tile provider has their own usage policy so this should be checked before enabling Open Street Map.
The search field for the Open Street Map works differently than searching on Google Maps. It matches producers by their name or address because it was easier to implement instead of matching place names all over the world.
Rails 4 introduced "automagically" modified cache keys, that included a digest in the key on any cache entry related to views. This is not what we want at all, fixed here with the `skip_digest: true` option.
