It may be related or it may not, but it's worth noticing, might be easier to reproduce and might shed some light. On a loaded system again, I clicked to close the right one of the many tabs of a FF window. The tab didn't close fast enough and, I know that I shouldn't, I clicked a second time. Two tabs closed. Hence, an action was taken on an object that wasn't yet visible at the place I clicked. This is contrary to instinctive expectation. It's a lookalike of this bug, but lookalikes may have the same solution.
