Collapsable view panel rows

I have a view panel within a section. The section is set to always be collapsed when the form is opened.

The view panel has a categorised column. When the user clicks the collapse/expand icon to collapse/expand the row in the view panel, the “parent” section collapses (it’s almost as if collapsing/expanding within the view panel is resubmitting the entire form)

Any ideas how I can stop this happening?
