Selectable, TreeNode: When using ImGuiSelectableFlags_AllowOverlap/ImGuiTreeNodeFlags_AllowOverlap and holding item held, overlapping widgets won't appear as hovered. (#6512, #3909)

Browse Source 
Essentially we are going to remove calls to SetItemAllowOverlap() and standardize the fact that only 'HoveredId == id' test from it is performed.
