Description

The icon of the application is sometimes replaced with the "prohibitory symbol" (not sure if this is the real name, just what came up when I searched) after an application update.

It happens with past Copy's (ie before the app is updated. the icon was fine with those entries ; then after the update, the icons for those same entries show up like this) but also with new Copy's made after the update (if It appeared for the past Copy's). After restarting Maccy, the icon is then visible.

Some notes: It also happens mostly with Firefox (but this is where I copy the most from): That application is updated very often (usually when I launch Firefox on a computer I don't use often, the update tab appears ; This is the situation I observe the issue often). The issue has happened over multiple versions of Maccy (I remember seeing it since I started using it a few months ago).

Steps to Reproduce

1. Copy from Firefox (or another app that is going to be udpated). Observe the icon is visible in the Maccy item list.
2. Update Firefox.
3. Observe the icon missing.
4. Restart Maccy and observe the icons show up again.
