Chrome in game mode running in strange resolution

I tried adding Chrome to Steam (using the Add to Steam option in the context menu). It technically worked. However, when starting it in game mode, chrome is shown in a strange resolution. www.whatismyscreenresolution.org reported the device resolution (correctly) as 2560x1600, but the browser viewport was only 1011x998.
Is there some trick to getting chrome to work in game mode?
