It's just a statement separator. Many add it automatically, needed or not.

It's not necessary, but it's there waiting just in case we decide to add
more statements to the event, e.g. (forced):

onmouseover="this.className='tableentry_active';alert(this.className)"

(Reference to window omitted for the sake of brevity.)

An analogy to CSS:

h1 {
color:#000;
background-color:#fff;
}

The second semicolon is not needed, but I tend to add it anyways.

Yes, that is an excellent idea. Very brief now.
