Are you, @Stefan_Huber , sure this is not caused by a filter? If so, it has always been like this.
When I open a modal on a filtered table, I can scroll through the records (rows) that pass the filter. If I open a modal on an unfiltered table, I can scroll through all the records.
When opening a modal from a (filtered) subtable, the filter doesn’t work at all and I can still scroll through all the records.
