app crashes while semantics is enalbled for automation testing in web

[vaishakNiveus]

Steps to reproduce

1)enable semantics in void main() using SemanticsBinding.instance.ensureSemantics();
2)wrap the typeahead widget with semantics and add a label
3)run the application in web
4)open inspect and click on "select an element in page to inspect " icon
5)click on typeahead textfield in screen and type some words select anything form the suggestion or press enter key after typing
6) app crashes without giving any error in console

Expected results

app is not supposed to crash

Actual results

while i tried running the app using "flutter run --verbose" getting the following error:-
