Relations Gridview with no results - header prevents links to be clicked

[lowap]

Prerequisites

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

1. generate view with giiant, with relations tabs using kartik grid
2. in case a relation doesn't have any actual related models, so the grid is empty

NOTE: as soon as there is one single related model in the grid, the problem doesn't exist anymore. In the base yii2 grid the problem doesn't exist as well. I'm using a very minimalistic basic gridview with an action column, and two data columns, without any fancy formatting.

Expected behavior and actual behavior

When I follow those steps, I see... I can't click on List All (related models), New (related model), Attach (related model) generated by giiant

I was expecting... To be able to click on these 3 buttons / links
