[Form] Autocomplete contains services, not form fields

[lovenunu]

Hi,

when in a controller, when I try to do:

$form->get('foo_field')->getData();

get's autocomplete method gives me my container's services, not the form fields. Moreover, it gives me Method 'getData' not found in class ... as get's return type is not FormInterface.
I think it's a confusion between form and controller's get method: when I try to ctrl+click on the method, the helper says Multiple implementations.

I'm using 0.11.98 and phpstorm 9.0.2

Oh, and thank you very much for all your work on this module !
