filterAttribute ignored in DataColumn when creating non-standard filters

[BelegUS]

Prerequisites

• I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• The issue still exists against the latest master branch of yii2-grid.
• This is not an usage question. I confirm having gone through and read the documentation and demos.
• This is not a general programming / coding question. (Those should be directed to the webtips Q & A forum).
• I have attempted to find the simplest possible steps to reproduce the issue.

Steps to reproduce the issue

1. Create some GridView
2. Setup a column with non-standard filterType eg. GridView::FILTER_SELECT_2 and filterAttribute different than this column's attribute

Expected behavior and actual behavior

When I follow those steps, I see that filter input created (eg. input's name) is for attribute value

I was expecting filter input to have filterAttribute used for filter creation (eg. for input's name). That's what filterAttribute is for and it works for "standard" filter types (eg. regular dropdown).

Problem's most likely that attribute is passed instead of filterAttribute in DataColumn::renderFilterCellContent():
