Description

During an upgrade, the upgrade wizard is very inefficient at the data that it pulls back. On larger upgrades, expanding groups in progress is practically unusable and can actually cause the browser to crash.

I recently observed this on a small upgrade but quickly opening and closing the active group (see screenshot). The expansion of groups/tasks just sat there spinning.

I think that the upgrade wizard needs to pull back a lot less data and possibly cache the majority of what it has in order to make it usable during a larger upgrade.
