Equirectangular Tile preview bad rendering - A black line is visible on the joint point until the tiles are loaded

Describe the bug

Hi Damien :)

I've found this issue in Equirectangular tile adapter.
It's present also in your official example.

The low quality preview of the pano is not connected right, if you see on the joint point (where the left and right side of the equirectangular picture are touching) there is a black line.
It seems an approximation issue of the width but I don't know.

This is because of the blur effect. There is no solution, the canvas blur uses the surroundng pixels even if they are outside the canvas bounds (and they are black).
