   @sarutak I am really sorry I missed your ping last week.
   The perf problem is resolved in https://github.com/apache/spark/pull/28806. 
If we want to avoid perf issue in the long term, I think we can avoid rendering 
the timeline by default. 
   I am +0 with the proposal. The pagination makes the visualization simpler, 
but also makes the UI usage more complex. If you insist, let's merge this one.

   > Even if no performance issue exists, lots of items rendered in one page 
can be too noisy.
   
   OK, how about we merge #28806 to 3.0/2.4 first. 
   And start the pagination from 3.1 if you insist?

   @sarutak I just created https://github.com/apache/spark/pull/28806.
   I believe downgrading the vis version is a safer solution. We need to hotfix 
this to Spark 3.0 ASAP

   Let me create a PR for downgrading to 4.21.0 now.

   So, I am actually -1 in this solution, for two reasons:
   1. if there are many stages in one job, the perf issue still exists
   2. the two paginations in one page seem weird.
   
   I tried a different version 4.21.0 from https://cdnjs.com/libraries/vis
   The infinite drawing issue seems better if the zoom is not enabled. 
   How about we changing to that version? or, just reverting 
https://github.com/apache/spark/pull/28192?

   @sarutak I just confirmed that the issue is caused by #28192 .  The issus 
can't be reproduced before the change.

   I think we should make the two pagination sections consistent
