Export defaultScrollSelectionIntoView

[12joan]

Description
Exports defaultScrollSelectionIntoView from slate-react, making it easier to extend rather than replace the default scrollSelectionIntoView behaviour.

Example

const SCROLLING = new WeakMap<Editor, boolean | undefined>()

// Custom scroll handler
const scrollSelectionIntoView = (editor: ReactEditor, domRange: DOMRange) => {
  if (SCROLLING.get(editor) ?? true) {
    defaultScrollSelectionIntoView(editor, domRange)
  }
}

const withoutScrolling = (editor: Editor, fn: () => void) => {
  const value = SCROLLING.get(editor) ?? true
  SCROLLING.set(editor, false)
  try {
    fn()
  } finally {
    SCROLLING.set(editor, value)
  }
}
