[post list] allow for edge swiping only

[SleepyScribe]

I saw this feature used in Feeder RSS reader. Wanted to bring it up here after accidentally downvoting myself when trying to swipe down through comments.

I also get hung up on scrolling because the app will catch and try to swipe an article (an issue that plagues every app with swipe actions). An option to only allow swiping from the corresponding edges would bring a ton of quality of life.

Something like a third of the content card, so it doesn't clash with gesture navigation. This would allow for the middle third to be scrolling only.
