Clipped, incorrect labels appear on exported map

[martinsellergren]

I choose "Generate static image" and select settings and area. All looks correct in the map:

Then I enter the generated URL in a browser and look at the image; clipped trash-labels appear that wasn't there before:

For example: lower left corner, "A. D &" appears. Mid lower left above label "H mart" the text "nford" appears.
The default Mapbox Streets-style was used.
