Steps to reproduce:
Try switching to another open window of orion with the default shortcut ⌘⇧↓.
It first scrolls to the bottom of the page.
With the second invokation it switches the window.
Doing this the other direction with ⌘⇧↑ also scrolls to the top first and the second press it switches the window.
The reason for this is probably that ⌘↓ and ⌘↑ are per default used in macos for scrolling pages to top / bottom and home/end of input.
Switching the window with the shortcut should switch it immediately and not scroll first.
