CanvasLayer does not align well with map at high zoomlevels

Attached is a file (canvas_glitch.html) of a modified version of the 
hello2d.html example file for CanvasLayer usage. It has a small canvas and 
begins at zoom level 21. It also contains a google.maps.Rectangle object with 
the same bounds as the canvas.

What steps will reproduce the problem?
1. Open the canvas_glitch.html file
2. Drag the map around
3. Watch the canvas misalign with the black rectangle and lag behind

Expected result:
Both the rectangle and the canvas should always be aligned.

Actual result:
The canvas lags behind the rectangle and it is often misaligned.
