I don’t install the fonts as outlined in the Arch Wiki as I do it a different way for improved Microsoft Office compatibility. By default, the ribbon (that collection of icons at the top of the program) in LibreOffice is more reminiscent of MS Office 9x than MS Office 365. Many embedded objects from MS Office don’t have perfect compatibility by default; to fix this, we can navigate to the Tools > Options > Load/Save > Microsoft Office and ensure all the boxes in the Embedded Objects section are ticked.
