/**
 * Replaces tab characters with spaces in text nodes that are inside elements styled with `white-space: pre-wrap`.
 *
 * This is a workaround for incorrect detection of pre-like formatting in the DOM converter for pasted Google Docs documents.
 * When an element uses `white-space: pre-wrap`, the editor reduces tab characters to a single space, causing
 * inconsistent spacing in pasted content. This function replaces tabs with spaces to ensure visual consistency.
 * This is intended as a temporary solution.
 *
 * See: https://github.com/ckeditor/ckeditor5/issues/18995
 *
 * @param documentFragment The `data.content` element obtained from the clipboard.
 * @param writer The upcast writer used to manipulate the view structure.
 * @param tabWidth The number of spaces to replace each tab with. Defaults to 8.
