fireworks are not boosting the elytras

I know other people have reported this bug, but not for this update. so, I noticed that elytra's aren't boosted anymore from using fireworks and as you can see in this video attachment, I didn't right click on blocks I also put on the f3 menu just incase its needed and sorry about my lagging laptop................. ok the file of the video wasn't allowed as it was too large and because I force crashed the game I relaunched the game to try and make a shorter video but when I tried, now the fireworks are boosting the elytra properly so the fix was to just restart the game lol though I can still show the crash report before it started working again
