In legacy canvas rendering the search box and the LoRAs list sat flush on a
fresh node, and their gap grew while the node was resized. The canvas branch
of applyAutocompleteTextLayoutFix tried to clear the custom sizing with
`delete`, but computeLayoutSize() lives on DOMWidgetImpl.prototype, so the
delete was a no-op. The text widget stayed growable (60-100px) and shared the
node's free space with the LoRAs widget, while its 60px min-height overflowed
the DOM widget's 10px bottom margin: the visible gap was
min(20, allocation - 60).
Shadow computeLayoutSize with an own undefined property and give the widget a
fixed computeSize. Adjacent ComfyUI DOM widgets normally keep a 2 * margin
(20px) gap, which is too wide for the search box + LoRA list pair, so
allocate elementHeight + 8px instead: the search box stays 60px and the gap
stays constant at any node height, matching Vue node mode.
Also document the overlay margin math and the prototype-shadowing constraint
in the dual-mode widget guide.
