Reordering headers does not reorder column data in >= 3.0

[MichalBryxi]

How to reproduce

Broken case

1. In docs go to any version that is v3.x.x and above
2. Click on "A Basic Table" section
3. Drag and drop one of the columns to other place
4. Notice that the header has changed position
5. Notice that the rest of the column data did not change position
6. Notice that the version of Ember here is v3.24.2

Working case

1. In docs go to any version that is below v3.x.x
2. Click on "A Basic Table" section
3. Drag and drop one of the columns to other place
4. Notice that the header has changed position
5. Notice that the rest of the column data also did change position
6. Notice that the version of Ember here is v3.12.0

Note: In my own app where this bug is present, I use:

"ember-table": "^2.2.3",
"ember-cli": "~3.25.2",

So it seems that the bug is introduced by higher version of ember rather than higher version of ember-table.

demo page has same bug

Made me wonder whether that means that ember inspector suffers from this bug as well or not. Well it does :)
