'subgrid' attribute invalid problem feedback
Develop component <my-button> based on web component, enable ShadowDom, and apply <slot> slot to insert sub-component <my-button-item> that also enables ShadowDom, and set grid layout of component element <my-button>. Invalid subgrid property set for <my-button-item> element (By the way,the subgrid property in the <my-button> component is valid)
