I could find a regression range, because it seems like the bug is intermittent. But I am sure that this is not a regression, because I could reproduce the issue on older builds from February 2020. Before that date the Instant evaluation option was not displayed.
I did notice three things:

  1. This issue reproduces on every web page you open.
  2. But it only happens once. If the options is disabled and anabled again, the Instant evaluation is displayed.
  3. If the web console is closed and opened again and the steps are repeted, then the issue is reproduced again.
