Steps to reproduce:
Enable vertical tab mode.
Expected behavior:
The close widget should be on the left side of the tab instead of the right, thus conforming with the close widget location in tabs and windows in other native macOS software.
In related unexpected behavior, the "mute tab" icon appears on the right side of vertical tabs ordinarilhy, but it scoots left and the close widget appears in its place when a tab is hovered over. This makes it very easy to try to accidentally close a tab when trying to merely mute it.
