When viewing item X from collection A, the breadcrumbs, as expected, are displayed as such:
A > X
Let’s say that on another tab, I open item Y on the same collection A, copy the URL and paste it on the first tab. The item displayed is Y as expected, but the breadcrumbs carry over the state from before and are displayed as such:
A > X > Y
This continues for however many other items I open and copy the URL in the first tab:
A > X > Y > Z and so on…
The breadcrumbs should only display
Collection > Item.
The breadcrumbs display
Collection > Item1 > ... > ItemX for however many item URLs I’ve pasted in the current tab.
