Filtering: Limit on State Events do not work

[pik]

For example the following filter will correctly apply "limit" : 0 to timeline but not to state.

{ "room": { "timeline" : { "limit" : 0 }, "state": { "limit": 0 }}

Since state is a graph-traversal it's not necessarily obvious how to add this functionality in a neat way (or if it is a sensible parameter to have). This is relevant for allowing low-bandwidth clients to render a Riot-Web interface (atm state event sets are not limited and /sync cannot complete). element-hq/element-web#2737

it's a feature that you can't limit or paginate state currently. i don't think the spec or anywhere else claims that you can.

@ara4n https://matrix.org/docs/spec/client_server/unstable.html#post-matrix-client-r0-user-userid-filter says that state is a RoomEventFilter, which takes an optional limit parameter.
