It also happens when clicking on a user of a users field inside an open drawer.

I think we need to fix with beforeunload event. Maybe we can solve this with the beforeunload listeners newly added to v5. I've tried to fix it in v4 and v5 but couldn't achieve it.

Something like that:

mounted() {
    this.$events.on("beforeunload", this.close);
},
destroyed() {
    this.$events.off("beforeunload", this.close);
},

@afbora Have you tried that? I don't think the get called when navigating around the Panel, just leaving the Panel/closing the browser.

@distantnative Yes, I tried but I thought it would work during page transitions but it didn't. Maybe I couldn't do it.
