Environment

• TeXstudio: 4.9.2
• Qt: 6.10.1 and compile with Qt 6.10.1 R
• OS: Windows 11
• TeX distribution: TeX Live 2025

Expected behavior

When pasting a copied table range from LibreOffice Calc into a tabular or tblr environment, TeXstudio should automatically detect the spreadsheet data and insert the corresponding LaTeX code (using & for columns and \\ for rows). This feature was previously restored in issue #4186 but seems to have stopped working.

Actual behavior

Instead of formatting the text as a LaTeX table, a dialog appears prompting to insert the clipboard content as an image (screenshot behavior). This indicates a regression of the fix implemented for issue #4186.

How to reproduce

1. Open LibreOffice Calc (tested with Version: 25.8.4.2).
2. Copy a range of cells (e.g., A1:C3).
3. Open TeXstudio 4.9.2.
4. Place the cursor inside a tabular or tblr environment in the editor.
5. Paste the content (Ctrl+V).
