Description of problem:
When searching for Pods or open the Pod list with "really long pod names" the list looks broken for some seconds (> 5 seconds sometimes). Looks like it requires an additional rerendering to fix this?! See attached gif.
Version-Release number of selected component (if applicable):
4.7 master dev build (commit c5c95818e0369d114252b6747f8c8d8370946c0a)
Steps to Reproduce:
1. Create some pods with "really long names" (> 40 characters to break in two lines in the pod list)
2. Open the search and search for resource type "Pod"
1. The cell/line height of the pod list doesn't update after all data are already loaded. See attached screenshot and gif.
2. When typing something to the search filter it looks like it trigger a re-rendering which fixes the cell/line heights.
Cell / line height should be match the content height right after showing the data without the requirement to trigger a re-rendering manually.

This is definitely an issue with table row virtualization since a re-render resolves the issue. Unfortunately, diagnosing and fixing it is very difficult as reproducing the conditions under which it occurs is elusive. I created a dev build of c5c95818e0369d114252b6747f8c8d8370946c0a, but could never reproduce using Chrome 87.0.4280.88 on MacOS. I will leave the bug open to see if it reproduces over time, but will lower the severity.
It looks like a consistent reproducer is to change the Project using the Project dropdown, so I'm setting the severity back to medium.
When the bug occurs, it appears the first time CellMeasurer runs, it gets a height of zero (because I assume the row contents haven’t rendered) and therefore falls back to the min height of 44. If, for whatever reason, a second render occurs, the bug is remediated. As best I can tell, this is only occurring on the Pods table. That could be either due to the number of columns or column management or both? I've reached out to Joe Caiani for an assist with debugging since Joe implemented the column management feature.
Reassigning to Debsmita as it appears changes in https://github.com/openshift/console/commit/d8999898eb5a393574da0a3e42c75c74c74b34dc#diff-88910eaad88244e5a1a05c0af91ff4e2691f9b916abf4a77575db876414b1b15 are the cause of the bug. Debsmita, the bug easily reproduces on the Nodes list page.
We did not have time to fix this issue this sprint. Will reevaluate and try to fix in next sprint.
