Pajamas nav > Reconsider parent item function

Purpose

In the Pajamas navigation a parent item both expands the subnav and takes a user to the first page of the subnav with the same click. Given that we don't make use of section overview pages this behavior feels a bit odd and misleading. While it's not difficult to determine where you landed, I don't think it's the most intuitive. It can also create a delay when you only wanted to access a page within that category, but have to wait for the first page to load before navigating where you wanted.

I'd like to propose that the parent item only expands/collapses the subnav list and does not have it's own destination.
