Additional Context

Also, I'm not sure if this should be a separate bug report, but rockets don't work/boost you when you hold them in your offhand while elytra flying.

Yes, this should be separate.

As for your bug report, I do believe this is Bedrock mechanics (try replicating it in a singleplayer world), so it might be harder to prevent.

As for the firework thing - I tested and apparently it doesn't work on Bedrock??

[NoozAbooz]

I tested these 2 in singleplayer and both are apparently bedrock mechanics. I assume both are bugs in the game. I'll make a issue on the mojang issue tracker then.

Since this is still a thing I will reopen as missing client feature for tracking purposes. Seems Mojang resolved this as works as intended because "not all differences between versions/platforms of Minecraft are bugs"... https://bugs.mojang.com/browse/MCPE-30816
