PR Summary
In JavaScript, the event handlers are called for both the element and also bubbled up from any children. If the Matplotlib figure is the only thing in the output, that's fine, as closing the figure when one of the
canvas
ordiv
s clears is the same as when theOutputArea
is cleared. However, if there are other outputs, such as widgets, we do not want to close the figure if one of them is cleared.As there's no way to clear just the figure output, only close the figure if the entire
OutputArea
div is cleared (i.e., the element we've attached to).Fixes #18638.
