Andreas ReinholdandClaude Opus 5 05236ecb3a Let a tooltip linger, and tell the screen reader what it says
A plain tooltip vanished the instant the pointer left, where M3 keeps one for
1.5s and shows only one at a time — these are popover="manual", so nothing was
closing the last one. A rich tooltip's bubble was never associated with its
trigger at all, so the explanation it exists to give was never announced; the
script now writes aria-describedby (and aria-haspopup/aria-expanded when it is
persistent) onto the focusable control in the trigger slot, and again after a
morph. Plan step 18, actions.md ACT-22, ACT-25.

/**
* `materialRichTooltip`: shows an `<x-rich-tooltip>`.
*
* Transient (the default): like a plain tooltip — after a short hover on a pointer that can hover,
* at once on keyboard focus, and it stays while the pointer moves onto the bubble to reach its
* actions. Persistent: a press on the trigger opens it as a light-dismiss popover.
*
* The trigger is pointed at the bubble with `aria-describedby`, so the explanation — the whole
* point of a rich tooltip — is read out with the control rather than never at all; a persistent
* one also says `aria-haspopup="dialog"` and whether it is open. The server cannot write any of
* it: the trigger comes from a slot, and only script knows which element in it takes the focus.
* A Livewire morph strips attributes the server did not render and gives the bubble a new id, so
* they are written again whenever the trigger is reached.
