Comment 4 for bug 892694

Nevermind - I misread the file attached in comment #1-

As originally reported:
> affects grids inserted/created inside transformed (e.g. scaled and/or rotated) groups.

The difference is that you didn't enter the group - if selecting an object within a group without actually entering the group, the grid is placed correctly. But as with layers, the bug exposes itself if you first enter the group [1] so that it gets the current drawing level, and then apply the extension.

[1] using the context menu entry, or by double-clicking it or by typing the keyboard shortcut 'Ctrl+Enter'
