Bug: 1D tracks and 2D map un-linked #354

The 1D track and 2D heatmap are unlinked, and move at different rates relative to each other.

Link: https://tinyurl.com/yagrxzev Move the map by dragging, and see how the 1D track position is untethered from the heatmap. Replicated in Opera and Chrome.

Strange, I can see the problem with the tinyURL you posted, but if I try to recreate the situation from scratch I can't. See this url for example, same tracks and location. https://tinyurl.com/ycqp3684

OK, I see it. The link you sent has a map pixel size != 1 (it's 2), it must have been zoomed with the lock, or via some other means. So the tracks are not accounting for the pixel size of the map when computing genomic location. I have no idea how far back this bug goes, and am not interested in searching. Can probably have a fix tomorrow sometime.
