Although not a bug, I also noticed here that an enhancement would be when manually mounting an existing EFI Boot filesystem, if the installer automatic filled in /boot/efi as the suggested mount point. That is, behave correspondingly and consistently as it does when mounting a swap file system by automatic fill in "swap" as mount point suggestion. Typically when setting up a dualboot installation with Expert Partitioner and Start with existing partitions, one just want to re-use the existing /boot/efi and swap file systems. When finally also "Import existing mount points" is re-implemented, this also come automatic here.
