FIX: Ignore max excerpt length for div excerpts too (#13058) 

We support two types of custom excerpts. It can be <div class="excerpt"> or <span class="excerpt">: b21f74060e/lib/excerpt_parser.rb (L120)

We also ignore max excerpt length for custom excerpts. But we forgot to process div when ignoring max length.
