How is Path of Building expected to behave?

When using import from built-in uniques list, all mods are kept

How does Path of Building behave?

When importing an item where first mod is unsupported and there is no implicit, then that mod will be lost. I've found two such items: Opportunity, Ultimate Life Flask and Lavianga's Spirits, Gargantuan Mana Flask.
This happens only with items that don't have an implicit. For example adding Zerphi's Genesis, Heavy Belt works correctly

How to reproduce the issue

1. Go to items tab
2. Select uniques for "Import from"
3. Find "Lavianga's Spirits, Gargantuan Mana Flask"
4. Observe that all mods are present in tooltip
5. Double-click the item
6. Observe that the first mod is lost

Screenshots

Start by reproducing the issue through the Items tab using the built-in unique import, especially Lavianga's Spirits and Opportunity, and trace the item import path. Done means unsupported first mods are retained for uniques without implicits while existing imports such as Zerphi's Genesis continue to work.
