Console error when exiting query builder

[maxpatiiuk]

1. Open production branch
2. Open query builder
3. Add any field
4. Open any other page
5. See an error in the console

Hint

Turns out the value of mirror is not always of type Element | null.

Solution

Replace:

      const mirror = (
        sortable as unknown as { readonly mirror: Element | null }
      ).mirror;
      if (mirror !== null) mirror.parentNode?.removeChild(mirror);

with:

      const mirror = (
        sortable as unknown as { readonly mirror?: Element | null }
      ).mirror;
      mirror?.parentNode?.removeChild(mirror);

It appears there was a typo in this issue's title.
Is it supposed to be 'Console error when exiting query builder'?
