Proposing a Final blocker:
"Any installer mechanism for resizing storage volumes must correctly attempt the requested operation. "
In this case, you cannot really cancel a previously requested resize, unless you reset all your changes completely (that is, however, an available workaround).
Discussed in 2013-12-11 Blocker Review Meeting . Voted as an RejectedBlocker and an AcceptedFreezeException. This is inconvenient, but can be easily worked around by hitting Reset All. A patch will be considered.
Does this still occur in F21 or F22?
I wasn't able to reproduce this bug in F22 Beta RC3, closing.
