[Discover] Document Explorer table is no longer browser searchable for off screen content

[ghudgins]

Kibana version: 8.1

Elasticsearch version: 8.1

Server OS version: Elastic Cloud

Browser version: Chromium Edge 95

Browser OS version: OSX

Original install method (e.g. download page, yum, from source, etc.): Cloud

Describe the bug: You cannot "cmd/ctrl + F" for Discover content that's out of view for document explorer.

Steps to reproduce:

1. Turn on doc explorer
2. Find some unique text that's "below the fold" / off screen
3. Scroll up so that unique text is out of view
4. Cmd/ctrl + f (browser find) for the unique text

Result: you cannot find the unique text

Expected behavior: You can find the unique text (this used to work on legacy table)

Great find. This is going to be an issue for some users. It's hard to say what percentage, but the browser find is a common use case. There was some discussion yesterday with @kertal about level of effort, and it seems like it might be high. This seems like a regression, with the caveat that there is 3rd party interference here.

A note about that, it also didn't work 100% with classic table. Why? in classic table 50 records are rendered by default, by scrolling down more records are rendered. The number of records rendered by Document explorer depends on the given screen height. So one solution would be: Buy a huge screen and rotate it 90°. In this case you might find more records using "cmd/ctrl + F". But this wouldn't be a good solution for sure. Just wanted to say: Fixing this would be more an enhancement then fixing a bug.

closing this in favor of #70799, because search among fetched result would be a way to improve this
