Close overlay if view is destroyed

[mstijak]

Sometimes the autocomplete overlay remains open even if the parent view is destroyed.

I managed to resolve that by adding the destroy callback in decoration.ts, but it doesn't seem like the right way to do it.

destroy: () => {
   reducer({ kind: ActionKind.close, view: null, trigger: null, range: null, filter: null, type: null });
},
update: (view, prevState) => {
   const prev = plugin.getState(prevState) as ActiveAutocompleteState;
   const next = plugin.getState(view.state) as ActiveAutocompleteState;

   const started = !prev.active && next.active;
   const stopped = prev.active && !next.active;
   const changed = next.active && !started && !stopped && prev.filter !== next.filter;

   const action: Omit<AutocompleteAction, 'kind'> = {
      view,
      trigger: next.trigger ?? (prev.trigger as string),
      filter: next.filter ?? prev.filter,
      range: next.range ?? (prev.range as FromTo),
      type: next.type ?? prev.type,
   };
   if (started) reducer({ ...action, kind: ActionKind.open });
   if (changed) reducer({ ...action, kind: ActionKind.filter });
   if (stopped) reducer({ ...action, kind: ActionKind.close });
}

If this does seem ok, I'll create a PR.

I added this part too.

handleDOMEvents: {
  blur: (view) => {
     closeAutocomplete(view);
  },
},
