When can we expect "insertWorksheetsFromBase64" completely supported for Excel on the Web?

The insertWorksheetsFromBase64 method is supported for Excel on Windows, Mac, and the web.
It's not supported for iOS. Additionally, in Excel on the web this method doesn't support source worksheets with PivotTable, Chart, Comment, or Slicer elements.
If those objects are present, the insertWorksheetsFromBase64 method returns the UnsupportedFeature error in Excel on the web.
