[Feature]: Search Menu Does Not Close After Clicking an Item
### What's the feature?

**Description:**
When clicking on an item from the search menu (e.g., "Quick Start"), the search menu remains open instead of disappearing automatically. Currently, users need to manually click somewhere on the screen to close the menu, which is not an ideal user experience.

**Steps to Reproduce:**

1. Go to https://tldraw.dev/ and open the search menu.
2. Search up and click on an item (e.g., "Quick Start").
3. Observe that the search menu remains open.
4. Click somewhere outside the menu to close it manually.

**Expected Behavior:**
The search menu should automatically close after clicking on an item.

**Actual Behavior:**
The search menu stays open, requiring an extra click on the screen to close it.

**Environment:**

Platform: MacOS

Browser: Chrome
