Unexpected behavior with legacy context (both shallow and mount)

[ms]

Current behavior

Cannot test legacy context behavior (mount and shallow, on the providing and on the consuming component) → .context either throws or returns an empty context depending on how it's used.

Expected behavior

.context returns the context somehow (after .dive or not, I'm not positive what the correct behavior should be)

Broken for me, too. Same environment.
