[QA] Gifts | Received a gift notification after purchasing a marketplace item

## Description

After buying an emote ("Spank That") using Polygon MANA, the user received a gift notifications in both the Marketplace and the Explorer client.

Buying a wearable using Marketplace Credits did not trigger the same issue.

## Steps to Reproduce

1. Buy an emote in the Marketplace using Polygon MANA.
2. Wait until the transaction has been completed.
3. Check the web and client notifications — you should see a notification saying that a user sent you a gift.

## Expected Behavior

The notification should indicate a successful purchase, not a gift from another user.

## Actual Behavior

Both the Marketplace and the Explorer client show a gift notification saying TagME#1fe0 sent the item as a gift.

## Environment

- **System:** macOS
- **Reproduction Index:** -

## Additional Notes

- Does not reproduce when purchasing with Marketplace Credits.
- Reproduces when purchasing with Polygon MANA.

Start by reproducing the issue with the listed Marketplace steps, comparing a Polygon MANA purchase with a Marketplace Credits purchase in both Marketplace and Explorer notifications. Trace the purchase and notification handling from that entry point; done means MANA purchases show a successful-purchase notification rather than a gift notification, while the credits flow remains unaffected.
