I think that is a problem with the current back-end version of Lemmy (0.17.4). I belivie that this is fixed in 0.18.0, but Lemmy.world has not been able to upgrade to it, as it is, presumably, badly optimized for larger Lemmy instances such as Lemmy.world.

It was intended functionality in 0.17.4. Pretty sure it was changed in 0.18.0 but .world has not upgraded because it's missing captcha functionality.

They tried to go to a release candidate of 0.18.1 that has captchas again but since it's not fully tested it didn't behave well apparently.

I’m a refugee from Apollo at the most recently failed social media place, and this is one of the biggest reasons I can’t, yet, call the Fed I’verse home. If I try to click a post it’s gone before my hand gets to it and it usually slips off the page before I catch up to it.

I see the same behavior in Chrome. I wonder if this is some poorly executed way to encourage users to be active on new posts. I do like that a similar feature auto-displays new comments. That doesn't bother me nearly as much as the new posts.
