Validator Gains and Losses fails if there are too many validators

[GDGitReporter]

On the Validator Gains & Losses page, there are several different panels that show the recent performance of each validator.

If you add more than 250 validators to Prysm, some panels stop working, and the page shows an error message that reads "Requested page size 256 can not be greater than max size 250" where 256 is the number of validator keystores that have been loaded.

The affected panels are the top panel, that shows aggregate data about recent validator performance, and the bottom panel that shows whether each validator attested correctly in the last round.

expected behavior today, but site needs to be reviewed for consistency

Update: The new UI breaks this worse. Now it puts up an error message that stops use of the page until you cancel it.

If you won't fix the bug, can you at least simplify it? Limit the display to the first 250 validators and leave it at that. Don't put up error dialog boxes, please.

will consider in a future release for this request.
