In positive characteristic, the ,normalizer, of a (connected) reductive subgroup of a (connected) reductive ,group, is not in general reductive. I communicated the example below in an emailed answer to a query in April 2002 (it took me some searching in old emails to find it!)

Centralizer -- from Wolfram MathWorld

26/3/2021, · The ,centralizer, of an element z ,of a group, G is the set of elements of G which commute with z, C_G(z)={x in G,xz=zx}. Likewise, the ,centralizer, of a subgroup H ,of a group, G is the set of elements of G which commute with every element of H, C_G(H)={x in G, forall h in H,xh=hx}. The ,centralizer, always contains the ,group, center of the ,group, and is contained in the corresponding ,normalizer,.
