Why do Zsh shell command prompt err or behave so messy, when user
input the entry with its buffer length is more than the current max
terminal column ?

What I usually see is the case with what -- I think -- you aredescribing, it is because there are non-printing control characters inthe prompt which get counted. Thus ZLE's count of characters on theline doesn't match what is visually on the line. Doing anything that(un)wraps the line at that point is ... at best ... a mess.

Proper use of %{ and %} sequences to keep ZLE from counting thenon-printing / control characters helps a lot.
