Через timeout можно

var bodyChat = document.querySelector('.form-body');
$('.float-chat').on('click', function (e) {
	bodyChat.classList.toggle('show');
	if (icms.chat.elementIsVis('.icms-footer__middle')) {
		setTimeout (() => {
			if (float_chat.style.color != "") {
				float_chat.style = ""
			} else {
				float_chat.style.backgroundColor = '#ecccbd';
				float_chat.style.color = '#1c223e';
			}
		}, 0);
	}
});
