Three more rules, all learned by shipping the bug first. Every one of them
produced a symptom that pointed nowhere near its cause.
RULE 5 REWRITTEN — `isConnected` lies about a panel that is a pane, in BOTH
directions:
- true when the panel is not here (it is in a pane window)
- FALSE when the panel is perfectly fine — the host detaches the element the
moment a pop-out starts, before the new window has loaded
Code that rebuilds on that `false` builds a SECOND panel while the host still
holds the first. Docking brings both home. The one the user can see is the
original, which the module no longer points at — so its close button closes the
other, invisible panel ("the X doesn't work"), and the chip gets re-attached to
the impostor ("the pop-out icon vanished"). Two baffling symptoms, one duplicate,
nothing in the stack trace.
Ask the pane system where the element is (`panes.isOpen(id)`), not the DOM.
RULE 6 (new) — a plugin that can be re-injected must be able to remove itself.
Without a teardown the second run duplicates every observer, timer and listener —
and leaves a stale pane registration, which is worse than untidy: `element` is
resolved LAZILY at open time, so the host gets a node from a dead instance. Pop
out, and it moves a panel nobody owns. Includes the teardown people forget:
panes.unregister().
RULE 1 EXTENDED — panel-internal id lookups. document.getElementById returns null
once the panel has moved, so every update it guards silently stops happening
while the user is looking at the panel. Search from the panel instead. Elements
outside the panel never move and are fine as they are — audit which is which.
