I just pushed a fix that solves this issue:

https://github.com/discourse/discourse/commit/9e54e0141e52afa7d02ebef76b800a8731682486

If you want to add this fix immediately you can add this css to your mobile stylesheet:

.fixed-modal {
  .modal-middle-container {
    margin-bottom: 0;
  }
  .modal-inner-container {
    max-height: 90vh;
    overflow: auto;
  }
}
