Auto-included shared contexts are not subject to the same scoping rules that manually included ones are

[myronmarston]

Currently, when you define a shared example group with metadata, the implementation does this:

mod = Module.new
(class << mod; self; end).__send__(:define_method, :included) do |host|
  host.class_exec(&block)
end
RSpec.configuration.include mod, *metadata_args

It delegates to configuration.include in order to make the shared group auto-included in example groups that have matching metadata.

There's a discrepancy with the scoping rules of shared example groups, though: if the shared group is defined within a nested group it is only available for manual inclusion (using include_context or similar) within that group or a nested group. With the metadata auto-inclusion, the shared group would still be included in any matching example group, even if it's "out of scope" according to our manual inclusion scoping rules.

We should probably address this but maybe in the 4.0 timeframe?

The change discussed in #1790 will solve this and I'm pretty sold on that, so I'm going to close this issue in favor of that one.
