Description

Where elevation: 4 is set, the shadow will disappear and some text will also disappear

Expected Results

Should be displayed like this

But it is displayed like this

Change the background color of the page to #fffffd or add marginTop: 1 to the outermost layer of this page
This can be displayed normally, but I think it should not be done
