I think part of the same issue: placing a new, undamaged tool, in the same hotbar slot as a recently-broken tool, can sometimes cause the new tool to disappear
The same occurs when opening chat via the / key, which is annoying because when pressing /, Minecraft automatically inserts / at the beginning, so it inserts two / characters.

I believe I am still experiencing this issue in 14w30c
Also cannot open trapdoors at build limit. Appears to open (client-side), but closes immediately, with build height message

I use the gnome window manager
This makes perfect sense as an explanation for the lack of breeding I'm seeing recently.
the same problem occurs when attempting to store into storage when explicitly setting a type of "long"
eg:
/execute store result storage t:seed aLong long 1 run seed
=> Seed: [5486814582284274048]
/data get storage t:seed aLong
=> Storage t:seed has the following contents: -847459968L
