Tab Center add-on (v1.36.0) sent by Erica was installed on a new clean profile.
Reverse Tab order is enabled.
Have 2 pinned tabs.
[Steps to reproduce]:
Open Firefox with the profile from prerequisites.
Right click on the second pinned tab.
Click on "Unpin Tab" option.
Observe what happens with the tabs order.
[Expected result]:
The unpinned tab keeps its place under the remaining pinned tab.
[Actual result]:
The unpinned tab moves above the remaining pinned tab, taking the first place in the tabs list.
[Notes]:
Dragging and dropping the unpinned tab under the remaining pinned tab will rearrange the tabs into their correct order: the pinned tab is moved first in the list and the unpinned tab moves under it.
Added a screen recording with the issue:
