Global search closes on typing
Similar to #1161 (closed), but I can't re-open that one.
Environment: Fedora 32, tested with Builder 3.36 from Fedora, 3.36 from Flathub, and 3.36.0-37-gea0b183b+flatpak-nightly from GNOME nightly.
- With any document open, the search collapses as soon as I start typing. Results start to appear, but at the same time that list collapses/disappears too.
- If I hit Ctrl-. as it's collapsing, I get the emoji picker pointed at the collapsed search widget.
- With no documents open, the search frequently collapses on typing as well, but it sometimes works. Behaviour doesn't seem to be determined by attempts, time, or previous global search box contents AFAICT.
