The "Travel to Player" and "Invite to Group" menu items are missing from the guild roster context menu. I can't test, because ZO_KeyboardGuildRosterManager is local, but I believe the issue is located in the function ZO_KeyboardGuildRosterManager:GuildRosterRow_OnMouseUp in the file guildroster_keyboard.lua.
The variable playerAlliance is used to check that the player and the target are in the same alliance, but playerAlliance is not declared within the scope of ZO_KeyboardGuildRosterManager:GuildRosterRow_OnMouseUp.
