Currently, when we select a type e.g. as the input or output type in the Function editor, and the search string matches against an alias, we show two lines, the first line with the label of the type, the second line with the alias it matches against.
It is slightly confusing to not show why a search result matches, but the current styling is even more confusing.
As a stop gap this task suggests to remove the line with the alias.
The full implementation about changing the styling is here: T323930
This task can be skipped and closed if instead the solution in T323930 is implemented.
