 It's possible I might have done something wrong when applying the patch,
 because I needed to get rid of the whitespace changes. Could you please
 check this?

 > OK, I will change it to {{{bgcolor}}}. I think the problem is not in
 whitespaces. The size of label background depends on the font size. I
 tested it on several font sizes and I got good results but obviously it
 doesn't work in general.

 It seems to change with zoom level, so I think you have to somehow convert
 between the pixel and geographic coordinates.
