+- Tooltips: made using SetItemTooltip()/IsItemHovered(ImGuiHoveredFlags_ForTooltip) defaults to
+  activate tooltips on disabled items. This is done by adding ImGuiHoveredFlags_AllowWhenDisabled
+  to the default value of style.HoverFlagsForTooltipMouse/HoverFlagsForTooltipNav. (##1485)
 - Nav: Tabbing always enable nav highlight when ImGuiConfigFlags_NavEnableKeyboard is set.
   Previously was inconsistent and only enabled when stepping through a non-input item.
