Check boxes that have a linked cell, and also have formatting (coloured background and coloured border) are lost when saving to a XLSX file.
Steps to Reproduce:
1. Create a Check box in Calc linked to a Cell
2. Provide some formatting to the checkbox (e.g. coloured background, border, etc.)
3. Save to XLSX file
The Check box is not linked to any cell
All of the formatting of the checkbox is lost in the XLSX file.
The linked cell and formatting should be retained.
User Profile Reset: No
The XLSX file when opened in Excel should have reproduced the checkbox as displayed in Calc.
