Documentation and code mismatch

[REWesker]

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.
• I have included a failing test as a pull request (Optional).

Steps to reproduce the issue

Sorry if this is wrong place to file documentation issue, I haven't found another
Documentation at https://demos.krajee.com/grid does not fully represent current code state

Expected behavior and actual behavior

per documentation:
responsiveWrap: boolean, whether the grid table columns will be responsively wrapped to a single column for small screen devices (less than 480px). Defaults to false. (emphasis mine)

at

yii2-grid/src/GridViewTrait.php

Line 409 in 6e02d25

public $responsiveWrap = true;

however the parameter is set to true by default

I can't determine which one of two options is expected behaviour
