Brief Description: Getting annoying lag when quickly breaking blocks directly down (mostly dirt) and sometimes jumping

Instructions:
1. Jump and place dirt below you to go to a higher position/Get to a high position over dirt.
2. Break quickly with a tool the blocks below you/Jump to a side

How many times did you recreate this bug?:

Around 75% of the times I did it (breaking blocks) without experiencing lag on any other action on the server at those times)

I guess the ones caught when jumping can be a "lag coincidence" as they don't happen too often, but through the other way they just happen so many times that I don't think they're just "regular" lag anymore.

Result: Falling Lag (not falling, forming a loop from the point I start falling)

Expected Result: Fall normally over the next block.

Evidence: N/A

I know I'm probably the only one/one of the few being affected by this. But since I've been in constant need of getting to higher places through placing dirt I have had many times to test this out when going down, and most of the times it forces me to do /spawn or /home. And as said before what I found curious is that I didn't experience any other kind of lag through other means.

Anyway, just posting this in case it could lead to information about a bug that might potentially affect all players.
