Configure parent Stacks header title option from nested Screen

[ghry5]

I have the following setup:

app/
  _layout.tsx                      <- Stack
  index.tsx
  search/
      _layout.tsx                  <- <BackgroundForSearch><Slot /></BackgroundForSearch>
      search-step-1.tsx            <- <Stack.Screen options={{ title: 'Search Step One'}} />
      search-step-2.tsx

I cannot seem to set the root Stacks header title from inside search-step1.
Thanks in advance.

After some debugging I have found that the id of the parent stack is the empty String "".
I tried using:

<Stack.Screen name="" options... />

This name gets passed to the useNavigation hook inside the expo-router Screen component. useNavigation is supposed to normalizer the id and fetch&return the closest parent with said id. However it contains the following:

const normalizedParent = React.useMemo(() => {
    if (!parent) {
        return null;
    }

This will return null when receiving the empty string thus not finding a parent.
Replacing this with:

const normalizedParent = React.useMemo(() => {
    if (parent === undefined || parent === null) {
        return null;
    }

would allow the empty string to pass and seems to fix my issue.
I would prefer however to just give the RootStack a fixed id like:

<Stack id="root" /> // or id="/" to make it work with relative paths

// in Screen component
<Stack.Screen name="root" options={{title: 'My Title'}} /> // or name="../../"
