Comment 5 for bug 1821367

So to be clear, may be I should rewording my issue. I two schematic sheet A, and sheet B. The root schematic "R" have a hierarchy sheet block that point to either A, or B. Whenever I change the file name of the hierarchy sheet block to A/B (difference than the other). Then open the hierarchy sheet block I got two problems:
  * The symbol references always get reset to "?" very time
  * Open the hierarchy sheet show the [?] block until save the project, and reopen hierarchy sheet. The root schematic don't need to be close.
