Map markers can appear too small

The bug

Named banner labels appear too small on maps that are placed in item frames on the ground. I thought it would be so cool to have a big map on the ground to walk on with the new labels and they are very hard to see. I made a 9x9 map with no zoom and put a "you are here" label on the center map. The more characters used in the label the smaller the text gets on the map. Would be perfect if the text stayed the same size as it does with a single character.
