Terminal 同样的操作 却没有变更

Start by reproducing the two calls shown in the issue on Sa-Token 1.43.0, comparing getSession().set("tenantId", 100) with getTerminalInfo().setExtra("tenantId", 100). Trace TerminalInfo and setExtra to determine where the extra data is stored and whether the change is visible afterward. Done means TerminalInfo extra contains the updated tenantId.
