weird map jiggle

[techieshark]

Search by school name for 'Helensburgh Public School', show nearby secondary schools, then click on map and drag up so you can pan the view and see the south. The map should show the south but it jerks back up north, perhaps to keep the secondary markers in view.

It's because of the high zoom in that particular scenario. Not sure how to fix that

@Lilith-Palmer - has some feedback

@techieshark Similar behavior is also occurring when an icon is close to the frame or filter box. Seems too jumpy - mapbox seemed to use a smaller buffer

[techieshark]

Yeah @Lilith-Palmer good catch. I think that's a different issue (in terms of the code needed to fix it) but it's a valid point (worth opening a new ticket for it).

One difference you might notice (which made mapbox seem less jumpy) is that if a marker is near the schools filter map control and you mouse over it, the marker's popup label appears in a separate layer beneath the filter box. So rather than automatically pan the map so the label can fit, it will be partly obscured by the filter box.

I think not moving the marker is a little more usable, since (a) there is enough unobscured text on the label that can a user can still figure out if that's what they want and can click on it, and (b) the part under the schools filter is just readable anyway due to the slight transparency. Here's another example:

The other factor that makes the google map seem more jerky is that when the map does move, it pans faster than the mapbox map defaulted to.

@techieshark Yes I did notice the different panning style. Google is very quick, hence it appears to be jumping around. I think it is the kind of behavior users may quickly learn/adapt too, but would be good to minimize. I'll get a new issue up.
