For the same reason that, in this case, the UK cannot make someone stateless it is not possible for Bangladesh to do so either. Her Bangladeshi citizenship is by blood and cannot be revoked while her UK citizenship is by naturalization and is therefore relatively easy to remove. This, of course, is discussing things from a rational/legal point of view which is really not the one that is important here; from a perspective of pure power politics the UK is the stronger party in this case so can simply declare a particular reality to be true and there is nothing the others can do about it.
