Ao invés de ter que verificar constantemente se você não está substituindo as propriedades anteriores, você pode usar a palavra-chave !important para garantir que essas propriedades sejam sempre aplicadas, independentemente da ordem ou da especificidade.

Dê a cada propriedade do seletor span[class~="sr-only"] uma palavra-chave !important. Não altere nenhum dos valores.

--hints--

O seletor span[class~="sr-only"] deve ter a propriedade border definida como 0 !important.

// log it
const text = new __helpers.CSSHelp(document).getStyle('span[class~="sr-only"]')?.cssText;
assert(text.includes('border: 0px !important;') || text.includes('border: 0px none !important'));

O seletor span[class~="sr-only"] deve ter a propriedade clip definida como rect(1px, 1px, 1px, 1px) !important.

O seletor span[class~="sr-only"] deve ter a propriedade clip-path definida como inset(50%) !important.

const text = new __helpers.CSSHelp(document).getStyle('span[class~="sr-only"]')?.cssText;
assert(text.includes('clip-path: inset(50%) !important;'));

O seletor span[class~="sr-only"] deve ter a propriedade -webkit-clip-path definida como inset(50%) !important.

// this one gets removed apparently
assert(code.includes('-webkit-clip-path: inset(50%) !important;'));

O seletor span[class~="sr-only"] deve ter a propriedade height definida como 1px !important.

const text = new __helpers.CSSHelp(document).getStyle('span[class~="sr-only"]')?.cssText;
assert(text.includes('height: 1px !important;'));

const text = new __helpers.CSSHelp(document).getStyle('span[class~="sr-only"]')?.cssText;

assert(text.includes('position: absolute !important;'));

O seletor span[class~="sr-only"] deve ter a propriedade overflow definida como hidden !important.

const text = new __helpers.CSSHelp(document).getStyle('span[class~="sr-only"]')?.cssText;
assert(text.includes('overflow: hidden !important;'));
