Opening the version restore view for an annotation with huge amounts of updateBucket actions can cause the page to crash because the maximum string length is reached in the string serialization of the update log.

Idea

The update action log contains the update groups with the specific update actions. The version restore view only inspects the actions to display what changed within a update group. Therefore, it is okay to truncate a update action group to the first 1000 items in my opinion. For now, we can limit this to groups where updateBucket is contained (so that we don't cause problems for the detection of split/merged tree nodes, for example).
