Nope. Parted does not magically delete it. Must have been deleted by another
tool. The moving of the extended partition from #4 to #3 is not done by parted.
When deleting #3 which starts at a sector after #4, then the extended partition
stays at #4.

I thought this might be related to BLKRRPART but deleting #3 with fdisk also
doesn't move #4 to #3. Can't reproduce with parted or fdisk.

The only explanation with parted would be deleting the extended partition as
well and recreating it as #3.
