To reproduce: 1. Go to https://whsieh.github.io/examples/find-and-replace.html 2. Click in one of the red boxes and type anything. Verify that cmd+z undoes the typing, and cmd+shift+z reapplies the typing. 3. Click the "Reload the subframe" button below. 4. Examine the "Edit" menu in the menu bar... Observe: the option to Undo is either grayed out, or replaced with one of Safari's undoable actions. Expected: Undo Typing Also note: cmd+z will not undo the typing done in step (1).
