Multiple issues with DevExtreme - Vue-Template 3.0

[objcxiaobai]

I created the project in the following way： npx -p devextreme-cli devextreme new vue-app xb-name --layout=side-nav-inner-toolbar --version=3 and npx -p devextreme-cli devextreme new vue-app app-name --layout=side-nav-outer-toolbar --version=3

The following questions were asked： 1.The layout of the two projects is exactly the same 2.The header and buttons in the Header-Toolbar component are white 3.The target property of the dx-context-menu component in the user-panel component does not work on the parent css
