Thank you for sharing the issue report, @kalegos

It seems that this issue appears when we have a container size defined, and we use Handsontable v12.0.0+. v11.1 works well https://jsfiddle.net/jvr9soq7/

On Firefox the error is

Uncaught TypeError: this.instance.getSelectedRangeLast() is undefined

but on Chrome, it's

Uncaught TypeError: Cannot read properties of undefined (reading 'highlight')

Hello,

We're experiencing the same issue. It was working fine under Handsontable v3.0.0. Issue appeared after we upgraded to v12.

We've also found a workaround for it and it seems like working fine ...

Ho @kalegos I have good news!

We just released Handsontable v13.1.0 where this issue is solved. Thank you again for reporting.
