fix(builder): update_props no longer wipes style on style: null

style: null fell through the shallow-merge branch's `value && typeof
value === 'object'` guard and hit the `p[key] = value` fallback, setting
p.style = null and losing every existing style key. Treat style: null (or
any other non-object style value) as "ignore this key" instead.
