Current behavior
When autocomplete is inside a modal and using appendTo='body' the suggestions appears not align with the input

Expected behavior
Suggestions and input should be align with each other

Minimal reproduction of the problem with instructions
Open dialog and see the difference of a autocomplete with appendTo and without

What is the motivation / use case for changing the behavior?
Once a autocomplete is inside a dialog, suggestions appear on dialog and the scroll is show up just to see the suggestions, i belive that isn't a the best behavior, and i need that suggestions appears out of dialog

The problem is kind of similiar at this issue: #6918
