Data table with groupRow="true" position of last row not is correct when use a p:rowExpansion

[mertsincan]

Reported By PRO User;

we have a datatable with the first column

<p:column headerText="#{headermethod}"width="15%" groupRow="true"><h:outputText />
</p:column>

When we expand any row of a groupRow we have that the last row of the grouping no longer respects the default position but is displayed under the column that has the attribute groupRow="true", this happens even when we have only one element and we click on the p:rowExpansion.

And

We have that to the first row is applied highlight and hower style that also highlights the column where the rowgroup is applied
