Azure Image Optimizer - Issue with transparent gifs

[MattXcz]

When I upload some gif with transparecy to azure, it moves the visible image to the left down corner. It can be seen here :

• Original picture (my own server) : https://backupcdn.mattx.cz/jezci-data/images/JezekLoad.gif (HERE)

• Picture with Optimizer (server in Azure) : https://cdn.mattx.cz/jezci-data/images/JezekLoad.gif (HERE)
