Calling refreshCells() with list of 3000+ cells makes vaading spreadsheet n

I am using vaadin spreadsheet addon version 1.1.6. In my project sheets in workbook will have minimum 40 rows and 60 columns. When user navigates between sheets I need to update cellstyles of around 3000+ cells. After applying styles I need to refresh the cells to see the changes in UI. I am using Spreadsheet.refreshCells() to refresh cells. Once I make this call UI hangs and I get a message in browser that cache.js is not responding. I would like to know if anyone facing this issue and found the resolution?
