＆＃34;表单在Gmail中被禁用＆＃34;

Question

Android Gmail App阻止输入类型提交。有人遇到过这类问题吗？帮助

代码：

<form th:action="${url}" th:object="${testToken}" method="post">
        <input type="hidden" th:value="${unique}" name="theUrl" /> 
        <input th:style="'border:0; height:60px; width:150px; background:url(' + |cid:${imageResourceName}| + ') no-repeat left top; cursor:pointer;'"
            type="submit" value="" />
    </form>
