web: Emoji picker closes when hitting spacebar

[stuartpb]

Describe the bug

Searching for an emoji with more than one word causes the emoji picker to close.

To Reproduce

Steps to reproduce the behavior:

1. Click the emoji picker button in the thread composer.
2. Type any text (or not), then hit the spacebar.

Expected behavior

The emoji picker should stay open and let you type a multi-word search query: this was the behavior fairly recently, probably just a few days ago.
