We use web jumps to allow our support engineers to connect to applications used by customers. Often more than one browser tab is used to diagnose issues. Where in one tab you open a certain page and in another tab another related page.
Ideally web jumps also get functionality that allows multiple tabs.
I notice RDP jumps have a setting that specifies if a subsequent connection should open a new session, the same could also be usefull for web jumps.
Today the limit of one connection prevents a lot of use cases.
