The primary fix is changing moz-box-ordinal-group to order in toolbox.css. This corrects the overlapping caused by the change from moz-box to flex as the default display model in version 113.
The moz-box-pack and moz-box-align were changed to the flexbox *-content equivalents, although I couldn't find their actual usage when inspecting the browser. They may need to be adjusted to *-items if necessary.
There's also a minor fix for the sidebar switcher collapsing due to flex: 1, so it now properly displays the full title of the current sidebar option that is selected.
