Yes I can confirm it is. the issue can be somewhat inconsistent but I promise it's still a problem
I made a new report MCPE-183495 yesterday on the jumping issue just for simplicity's sake, and also in case it does turn out to be a separate issue (Although you're probably right that it's the same).
Still an issue in 1.21.1 Hotfix
It doesn't matter much, but I reported the jumping issue along with moving faster than moving blocks in May 2023 (this report was made in June 2023) and my report was marked as a duplicate.
Although I suppose this report has better technical wording, I don't think mine should've been marked as that since I also covered the separate issue with jumping as well.
Can y'all please fix this in the next hotfix? It makes building in creative so much more difficult
I wouldn't consider them the same. Before you were able to hold down both the up and down buttons and crouch while flying; now you can't.
The issue seems to be resolved now
It's also a parity issue, since on Java wardens aren't attracted by pressure plates they stand on. And still, it's quite annoying as a map-maker since I love the idea of having stealthy areas with wardens, and naturally you want to use pressure plates to add difficulty as an obstacle for the player. But of course, this issue makes that pretty much impossible. Is it niche? Definitely, but I also just think it's pretty silly that the most powerful mob in the game can be stumped with a pressure plate.
IF not anything else, I'm hoping Mojang will change this just for parity's sake.
