Pre-conditions: there is hierarchical category tree, lets say parentCategory and its child childCategory
Open for example page properties and check categories selection: needed categories will be available in the list and displayed in correct hierarchical order. Choose parentCategory for assigning it to the page -> open categories list again: childCategory won't be available as its parent was removed from the list (same if trying to search for child typing text directly) - same issue exists in other pages where categories selection for assigning/filtering is available.
As there should be no limitation for categories assigning/filtering, it would be better to disable already chosen categories instead of removing them from selection list like it is now.
