Throws Unhandled Exception when direction is AxisDirection.up
If I ignore the exception, everything works as expected, not sure why this occurs.
This is happened when I have 30+ items, and scroll the suggestion box with mouse wheel or scrollbar. It will emit the exception per scroll trigger, so the below looks long but just one same exception.

flutter_typehead: flutter_typeahead: ^3.2.4
Edit:
It's easy to reproduce by adding direction: AxisDirection.up, in the example of _FormExampleState. So the bug is causing by direction. In addition, I'm using windows desktop for the test.
If I comment out these to suggestionsList only, no exceptions. So It must happen in FractionalTranslation.
