SharePoint online Column Formatting

Hi

I have a sharePoint multiline column (rich text enabled) in a library and using flow I have added data as:

<div>item1</div><div>item2</div>..

When I view the library I can see the items arranged vertically (as I want) but the view gets truncated after the 4th item, otherwise the row height would get too large.

Is it possible, on hover over that all the items in the column field can be shown- maybe in a custom card or something else.

I've added divs around every item but havent added a container div as this gets difficult to implement through flow, especially when I need to update and maintain previous data.

I've looked at MS docs but there is no example where an outer div is not used. - https://docs.microsoft.com/en-us/sharepoint/dev/declarative-customization/column-formatting#get-started-with-column-formatting
