Do NOT click once on the favicon to select it after it's downloaded.

Context

KPXC 2.1.3 on Mac OS X 10.12.3. I just started using it today.
The DB is shared via Dropbox.
The DB was made last night, on Windows, using KPXC 2.1.3, from an imported v1 DB made with the old KeePassX (not sure which version, but probably really old, like maybe 0.4). I have not made edits to this DB yet on KPXC. It started with default icons everywhere.

So I've relaunched KPXC, went again into the Icon menu, actually clicked once on the downloaded favicon to select it, clicked OK, and it was fine.

Your Environment

• KeePassXC version/commit used: 2.1.3
• Qt version (e.g. Qt 5.3): 5.8.0
• Compiler (e.g. Clang++3.6.0): no idea, I've installed it from the binary installer
• Operating System and version: Mac OS X 10.12.3
