paste-from-office/filters/replacetabswithinprewithspaces

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.
