A small brewer leased a commercial building from a landlord for a period of five years. The brewer installed tanks, pipes, and other equipment for his brewing operations and began operations. Two years later, the landlord mortgaged the property to a bank to secure a loan. The landlord informed the bank that the building was currently leased to the brewer. The bank recorded its mortgage but the brewer was not informed of the mortgage. Six months before the lease term was up, the landlord defaulted on the loan. The bank foreclosed on the mortgage and acquired title to the property. When the brewer began removing his equipment from the building shortly before the end of the lease term, the bank sought an injunction to prevent him from doing so. If the court denies the bank's injunction, what will be the likely explanation
