Bounding box wrongly displayed

[letmaik]

The bounding box {"type": "Polygon", "coordinates": [[[1.8, 60.9], [1.8, 49.2], [-13.4, 49.2], [-13.4, 60.9], [1.8, 60.9]]]} in the spatial field is displayed like:

whereas it should be:

Same for me. I tried with other polygons such as:

{"type":"Polygon","coordinates":[[[102.919921875,11.695272733029402],[102.919921875,14.944784875088372],[107.75390625,14.944784875088372],[107.75390625,11.695272733029402],[102.919921875,11.695272733029402]]]}

Which are represented correctly.

Could it be a precision thing?
