### Instance

### Browser

Safari on iOS 18.2

### Bug description

I've repeatedly noticed that Notifications entries seem to disappear when a person repeatedly interacts with more than one message (see below for details).

### To reproduce

1. account 🅰️ : ✍️ post a message 1️⃣
1. account 🅱️ : ⭐ like 🅰️'s message 1️⃣
1. account 🅱️ : 🚀 boost 🅰️'s message 1️⃣
1. account 🅰️ : Notifications shows "🅱️ boosted and liked your post 1️⃣"
1. account 🅰️ : ✍️ post another message 2️⃣
1. account 🅱️ : ⭐ like 🅰️'s message 2️⃣
1. account 🅰️ : Notifications shows "🅱️ liked 2 of your posts", with no more indication of 1️⃣ having been boosted

### Expected behavior

In the final step above, there should still be an entry "🅱️ boosted your post 1️⃣" in addition to "🅱️ liked 2 of your posts"
