Spreadsheet Version 2.1.1 and laters. Error in merged cells

v8.5.1 - Vaadin Framework
v2.1.1 - Spreadsheet

When merging cells in the last columns, the merged area is doubled in the previous columns. I show a video replicating the error.

Thanks for reporting, it can be easily reproduced with demo.vaadin.com/spreadsheet

This could be related to

#374

v8.5.1 - Vaadin Framework

Have you tested this with Vaadin 8.12.1 ?

Thanks for answering

I just tested with 8.12.1 and the problem continues.
It is a critical bug when using cell merge
