i18n Autocomplete not taking linguistic context into account

When adding a Geographic type entry, autocomplete should offer content according to the linguistic context selected.

In the dataset used for this test, the ontology only included English country names, so it was to be expected that using autocomplete in fr_CA context wouldn't pull "Suède". However, neither was is it expected to offer "Sweden", which it did.

I suspected the dataset might have caused the problem, so I created a "Suède" entry while in the fr_CA context, expecting it would have the correct linguistic label and wouldn't get pulled in the en_US context - but it did nonetheless.
