I also have it staged on a PPA for anyone that would like to test in advance of SRU team's review.

Bug description:
  [IMPACT]
  fwupd 1.9.x attempts to detect the correct ESP to use, but since it's been opened up to all FAT32 partitions, there have been some false positives such as:

  /run/media/root/PQSERVICE does not have sufficient space, required
  90,1 MB, got 51,2 MB

  PQSERVICE is a recovery partition on Lenovo systems and NOT an ESP.
  In order to fix this, heuristics are added to fwupd to skip known
  recovery partitions while still allowing to install on FAT32
  partitions that look like ESPs.

  [TEST PLAN]

  Test that fwupd enumerates ESP properly

  [Where problems occur]

  If a user manually names their ESP using anything in the heuristics
  list it will no longer be identified properly.
