[.Net 1.8.9] Can't open XLSB files using LoadDataFilterOption other than LoadDataFilterOption.All


We’ve ran into an issue where it appears we can’t open XLSB files with any LoadDataFilterOption other than LoadDataFilterOption.All. Is this because of the way the data is loaded with XLSB files by Excel? I have attached a zip containing code to recreate the issue and an example XLSB file.
