Wrong ordering of datasets by used/available space in the web ui

Ordering dataset by space used/available in Storage/Pools orders without considering storage units. Eg:

1.55 TiB
1.79 GiB <---
1.80 TiB
2.76 GiB <---
3.16 TiB
34.10 GiB <---
52.28 GiB <---
81.38 KiB <------
265.96 GiB <---
398.96 GiB <---
