Icon symbol size in data browser is too big

[IgnacioHeredia]

Is your feature request related to a problem? Please describe. Hi all,

minor enhancement here.

In the data browser, the icon symbol (ie. the white circle) size seem to fill the full square color, preventing from clearly visualizing the color of the marker. In contrast, in the marker show in the map, the symbol seems to have a much more "reasonable" size (ie. ~1/3 of the marker size).

Describe the solution you'd like Smaller icon symbols in the data browser, like in the map.
