Describe the issue you are experiencing

A 3 column dashboard is a popular layout for HA. I notice on my wall mounted 9,6 inch iPad with Safari browser that the 3 column homepage in the Default view is shown in 2 columns when recreated in the Sections view: I simply copy-pasted all content from the default dashboard into 6 sections, setuo over 3 columns. However, on the iPad the Sections-page is shown in two columns. Seems that the total pixel width slightly differs looking at the white area between the columns??
