"The label", or "the labels"?
The problem of "hover the control if the label is hovered" is simple:
the label already has a reference to the control it's labeling; when an
element enters hover state you at worst have to deal with one other
element (plus their ancestors) entering hover state.
And even that gets a bit complicated given the "ancestors" thing.
The backreference, however, is a one-to-many relationship, which makes
things quite complicated, or fairly slow, or both, when multiple labels
label the same form control. So I would be a bit careful here.
