wpsjs开发加载项目，设置ribbon.xml垂直布局的按钮和水平布局的按钮高度不一致

想通过自定义加载项的开发复刻WPS AI部分功能提供给企业内部使用。但是通过设置ribbon文件设置按钮后如下图一所示，高度无法对齐。图二为WPS AI中功能。代码片段为 <group id="commonGroup" label="commonGroup"> <box id="boxRevsion1" boxStyle="vertical" visible="true"> <button id="btnExpansion" label="扩写" onAction="ribbon.OnAction" getEnabled="ribbon.OnGetEnabled" getImage="ribbon.GetImage" visible="true" size="large" /> <button id="btnAbbreviation" label="缩写" onAction="ribbon.OnAction" getEnabled="ribbon.OnGetEnabled" getImage="ribbon.GetImage" visible="true" size="large" /> </box> <menu id="menuPolish" label="润色" showLabel="true" onAction="ribbon.OnAction" getEnabled="ribbon.OnGetEnabled" getImage="ribbon.GetImage" visible="true" size="large"> <button id="itemPolish1" label="快速润色" /> <menuSeparator id="separator1" /> <button id="itemPolish2" label="更正式" /> <button id="itemPolish3" label="更活泼" /> </menu> </group>
