Description
Tried nesting my custom completer in a fuzzy completer and my display tag was overwritten everywhere. Might be that FuzzyCompleter adjusts the style based on "text" instead of "display".
How to re-create:
class MyCustomCompleter(Completer):
def get_completions(self, document, complete_event):
yield Completion(text="123", display="456", start_position=0)
text = prompt('> ', completer=FuzzyCompleter(MyCustomCompleter()))

Start with FuzzyCompleter and reproduce the issue using the MyCustomCompleter example, focusing on how Completion.text and Completion.display are handled. Confirm that nesting the custom completer preserves the display value "456" rather than replacing it with "123".
