"Abaixos-assinados" ou "Abaixo-assinados": Qual a forma correta?

A palavra abaixo-assinado é composta por duas partes: abaixo e assinado. Ambas são consideradas palavras independentes e, portanto, seguem as regras de pluralização da língua portuguesa:

[{"selector":"#anim-a9bda9a5-29f9-4a5e-a696-d5490c9141eb [data-leaf-element=\"true\"]","keyframes":{"transform":["translate(0%, 0%) scale(1.5)","translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}] [{"selector":"#anim-6fd238fe-5c03-4058-b210-30cd85c19ebc","keyframes":{"transform":["translate3d(115.92356%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-19f0aa4a-7610-4d1c-9708-334e6b0ff1b2","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-5a94f7a1-8fb1-4d2c-b953-a18243e5ef5b","keyframes":{"transform":["scale(0.15)","scale(1)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"forwards"}]

Por isso, o plural correto de abaixo-assinado é abaixo-assinados.

[{"selector":"#anim-5d0b7f48-5d04-4d94-a4a4-6fb25c6b31d3","keyframes":{"transform":["translate3d(115.92356%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-b696cb57-275c-47fe-b9ef-702347da2dab","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-e1ff44df-b0fb-42ee-82b0-079752113bfd","keyframes":{"transform":["scale(0.15)","scale(1)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"forwards"}] [{"selector":"#anim-1b6c7871-c34a-4919-b885-d5e91cd86a78 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate(0%, 0%) scale(1.5)","translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

– Abaixo não varia em número, permanecendo invariável no plural. – Assinado flexiona em número, assumindo a forma assinados no plural.
