widgets in map wrongly align with a specific config

[MV88]

Description

How to reproduce

• use this config

{
        "name": "Widgets",
        "cfg": {
          "cols": { "md": 48, "xxs": 1 },
          "rowHeight": 10,
          "defaults": {
            "initialSize": {
              "h": 8,
              "w": 8
            }
          }
        }
      }

• open a map with some widgets in single widget layout (resize window until it triggers)

Expected Result

to see widgets panel correctly
Current Result

it goes very below and the widget is not fully visible, partially hidden
this is due to the fact that rowHeight from configuration affect the baseHeight here
