Cherry pick smaller WWT table to short demo

[patudom]

(From #748).

This seemed like a pretty straightforward cherry-pick, but when I run it, I have to switch back and forth btw guidelines several times to get the green dots, so seems like this update is not solving the issue. ☹️

If someone else would like to give it a go, please let me know what you find. Don't forget that you have to set CDS_DISABLE_DB=true in the command line

In case it's in any way related, I got this error when I killed the process:
