Identifier lookups that resolve into a named item's host dispatch called GetIDsOfNames on the host for every access, while native vbscript resolves a name once and reuses the DISPID afterwards. Building on the unified member tree, collapse the lookup_global_vars and lookup_global_funcs pair into a single member lookup that also understands host properties, and record a resolved host DISPID as a SCRIPTDISP_HOSTPROP entry in the named item's script dispatch. A subsequent lookup finds the entry directly and never queries the host dispatch again. The entry lives and dies with the named item's dispatch, and is kept out of the script dispatch's own member enumeration. A later Dim or declaration of the same name shadows the cached host property, matching native precedence. This replaces the separate per-named-item DISPID cache (!11136) with a single representation in the global tree. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/11211
