This PR addresses a bug in the Kubernetes session join logic where a joined session could hang under specific conditions. The issue occurred when one or more peers triggered multiple terminal resize events in rapid succession. The client handling the resize was only performing a single resize operation and failing to respond to subsequent events, resulting in the terminal becoming unresponsive. This led to a state where session data was no longer displayed to moderators or observers, effectively freezing the shared session view. The fix ensures proper handling of repeated resize events to maintain session responsiveness and continuity. Signed-off-by: Tiago Silva <tiago.silva@goteleport.com>
