Original description

I saw some reports of this issue for earlier versions, and in this report ( MC-159447) the issue was supposedly fixed. I didn't know what to do to report a bug and when trying to sign in my minecraft.net account info did not work so I made a new account to post this bug report. After seeing many snapshots talking about all these fixes I did not see any talk about fixing bees being stuck to fences. Hope I'm not the only one dealing with this. I have a couple screenshots and I put in blocks from 1.16 in it to show that was the version I was playing (1.16 pre5 specifically). 

Hope this issue can be resolved before 1.16 officially releases.
