Autocompletion renders equal signatures for two different suggestions

[koperagen]

On the first screen, we see two variants with Predicate<Int> type, but on the second screen an actual type of the resolved variant is Predicate<ColumnWithPath<Int>>

@koperagen can't reproduce in Jupyter notebook... @strangepleasures how did you implement completion in Datalore? Where should we file an issue?
