Subject

In the filters and the forms I noticed that in the field's type 'entity type' area is too tight.
I think that it may be connected with select2 configuration.

In ModelAutocompleteType is OK.
In the 3.45.2 version this area was OK (wide).

Steps to reproduce

Open filters, select field with select2 (entitytype).

Expected results

wide select2 field

Actual results

Same bug here with 3.46.0 in all my dropdown ( date, list, etc ) ;)

I figured out why => select2 got initialized 2 times. The first time was from AdminBundle then the CoreBundle override it.
