Description

Note that we have introduced a dump link on the backpressure page in FLINK-29996(Figure 1), which helps to check what are the corresponding subtask doing more easily.

But we still have to search for the corresponding call stack of the back-pressured subtask from the whole TaskManager thread dumps, it's not convenient enough.

Therefore, I would like to trigger the search for the editor automatically after redirecting from the backpressure tab, which will help to scroll the thread dumps to the corresponding call stack of the back-pressured subtask (As shown in Figure 2).
