Canvas source doesn't render in world repeats at edges

[ansis]

The example above shows our requirement of syncing a canvas source (represented by a green border with blue background) such that it is always centered in the map container and is equal to the pixel width of one world. The bug can be seen in the rightmost world repeat, where the canvas is not visible. If you pan the map east past the antimeridian, the canvases render correctly. This also happens when zooming. For example, zooming into the left instance of India from the initial view will cause the canvas to disappear once the map bounds no longer contains the antimeridian.

browser: Chrome

Steps to Trigger Behavior

1. Add canvas source that covers large part of the world and crosses antimeridian
2. Zoom out
3. See missing copy at right edge of map
