Worked: ???

Short description of error
Select hierarchy operation deselects objects and select only one hierarchy, only for active object/collection.
It is very confusing and make impossible to select content of 2+ collections (or parents) at once and operate with complex scenes and bunches of objects.

I think it is because Active object paradigm was not handled properly during redesign.
Deleting used to work perfectly (video with 2.9.2 Alpha).

Also I am finding the fact that outliner hierachy tools stand for actual parenting hierarchy pretty confusing, since collections in outliner have their own complex hierarchies independent from parenting.
So names like "Select hierarchy" and "Delete hierarchy" in such a completely hierarchical tool as outliner are confusing.

@1D_Inc
hm, yes, Delete work as expected. So here we have inconsistency at least.

What naming do you suggest instead «X hierarchy»?

Will confirm for now because this looks inconsistent.

At the end it is up to developers to consider this as a bug or else.

I am not much fluent in English, but "Select Parented" probably would prevent me from trying to select a part of collection's hierarchy.

It's actually selecting for the first tree element and not the active one.
I'll see whether I can fix this

@PratikPB2123 @JulianEisel When it comes to selecting collection/object hierarchies we should also get D15351 into master.

@JulienKaspar hi, D15351 looks useful. Want me to test the patch? :)

@PratikPB2123 Sure. At least test it if it fixes the issues of this bug report.
But I think the patch was already tested a lot in terms of usability. It just needs a technical review at this point I think.

A question though - what will happen to outliner's menu functionality?

Also ctrl/shift assignment is still questionable - especially when you use shift to add to a selection in the viewport, but have to use ctrl for the same operation in outliner.
Originally, ctrl for adding item to a selection was assigned in GUI-based OS (like win 95), because it was not supposed to be used often when work with files and folder, so ctrl/shift assignment didnt had any priorities or advantages because of a low relevance in that case.
In 3D CG the situation is completely different - you add to a selection like all the time, starting from mesh subentities and ending with objects, so Shift has a huge advantage over ctrl because of a better key acessibility.
Originally Blender had Shift for all adding operations, and it was a nice choice that provided unified behaviour and solved the issue.
