Map shifts on zoom

[danieldegroot2]

for both https://v2.sondehub.org/ and https://tracker.sondehub.org/ and https://amateur.sondehub.org/

Minor visual remark;

When zooming in or out using either the mouse wheel or the zoom controls, sometimes the map shifts back and forth slightly,

• to correct for the map window size, data layer loading lag, or similar; or
• due to an issue with the leaflet implementation or library.
  It is best visible using the 'Mapnik' style (on other maps usually known as 'OSM Standard').

It does not appear, at least not immediately, on mobile iOS Safari.
