Right, inert="" has no effect on .click() (and certainly has no effect on
manual dispatch; that works on anything, it just doesn't usually do
anything surprising -- for example, it doesn't click a button or link the
way that .click() does.) The inert="" attribute basically just makes
clicks not work and prevents focusing (so you can't activate things by
