System Information
Operating system:windows10
Graphics card:gtx1070

Blender Version
Broken:blender-2.83-a210b8297f5a-windows64
Worked: 2.82

Short description of error
Object deleted when deleting a modifier or any subobject (material, modifier...)

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

add a cube
add a multires modifier
select multires modifier, you can see that the object (don't know if it's the right tem, the root object with the orange triangle containing the hierarchy) is selected too (not in 2.82)
delete the modifier
the object is deleted also

I assume this is about the Outliner.

select multires modifier, you can see that the object (don't know if it's the right tem, the root object with the orange triangle containing the hierarchy) is selected too (not in 2.82)

I assume this is done via the Outliner Context Menu?

This has changed in fe7528ee91
From that commit on, you cannot spawn a Context Menu of type Outliner Data Operation on a modifier anymore, instead a Context Menu of type Object is spawned -- always.
In that respect, this is actually doing the right thing, you are deleting the object, not a modifier (deleting a modifier has never been possible afaict -- not even with the Outliner Data Operation context mennu, there is no Delete in that menu...)

Worked: 2.82

Doubt that (see above), deleting a modifier has never been possible afaict -- not even with the Outliner Data Operation context mennu, there is no Delete in that menu...

So, I dont think it was intended to disallow the context menu of type Outliner Data Operation on modifiers in fe7528ee91, @Zachman? shouldnt that still be possible? [even though it has limited use for modifiers tbh.]
CC @dfelinto, @WilliamReynish

If we stick to only having the Object context menu for modifiers in the outliner, then this should not be considered a bug and could be closed I guess...
Will at least confirm for now, other classification is up to others (since it is not obvious from that commit if these side-effects were intended)

We should address this, in the same way that deleting both objects and collections should be possible using the same shortcut and form the context menu.

I believe @Zachman is looking into this. However, it's not a bug, but simply a todo.

Yes in the outliner
I have done a short video to show you the difference of behaviour between the two versions

2.83 more accurately shows you what is selected. If you select a modifier, the parent object is also selected. The issue is not that, but the fact that you can't delete modifiers or constraints from the Outliner, which is clearly a todo, not really a bug.

Ok I see what you mean
In fact you can delete a modifier, you have to left clic with ctrl on the object so the object get deselected but not the modifier and then with a right clic access to delete in the context menu but it's far from being straightforward

As @WilliamReynish said, 2.83 is more accurate by actually selecting datablock parents (i.e. selecting a modifier in the outliner will show the parent object as selected). The issue with this is that the context menu has a few different Delete entries and they are dependent on the selection. If only modifiers (or other datablocks) are selected, the delete operator for those datablocks is shown in the context menu. But if any objects are part of the outliner selection, the Object Delete menu entry is shown.

So yes, deleting modifiers worked in 2.82 and does not yet in 2.83. The context menu will need to be fixed to be more contextually aware of which datatype was the target of the right-click.
