Thank you @lkovesdi for attaching the reproduction example, the issue seems to come from onCellClick handler which doesn't work properly in the case of singleSelect. I suspect this is due to the backdrop of the Select component.

We need to look further into this recipe and fix this specific issue. Feel free to open a PR for the fix if you want.
