[tag:bug] [tag:status-completed] [GH #172](https://github.com/StackExchange/Stacks-Editor/issues/172) The undo/redo buttons (which may only show up on mobile?) always look enabled even if I haven't done anything: [](https://i.sstatic.net/hZQPT.jpg) The table button however looks disabled because I selected some text in the answer. They used to be disabled if there was nothing to undo/redo (though that had its own bugs).
