Steps to reproduce:
When I add addon icons to the toolbar, after only a couple of minutes, or if I close and open Orion, the "New Tab" icon disapears. No matter how many times or where will I place it in the toolbar, the new tab icon will disapear again, and it happens only with the new tab icon. Additionaly, it happens to more than one installation, in more than one of my devices so it's reproducable on my side.
Expected behavior:
New Tab toolbar icon should stay at the place the user places it at all times.
Orion, OS version; hardware type:
Version 0.99.122-beta (WebKit 615.1.11.7)
MacBook Pro (macOS Ventura 13.1 build 22C65)
