Bug reproduced on Archlinux with latest stable release of LibreOffice (5.4.2) and on Gnome with both Wayland and Xorg.
If user try to do a quick double-click on the menu under the titlebar, when those menu are closed the second click is ignored and it's interpreted as a single click.
This is not the case when the menu is open: both click are interpreted and menu is closed with the first click, then reopened with the second one.
The behavior when the menu is closed might be a design choice: I can't know.
If it's not, it should be fixed, if it is I guess behavior should be consistent depending on the menu being closed or opened: either double-clicks are interpreted as single ones in both cases, or it works as double-click in both cases too.
Could you please record an screenshot for clarification?
Could you please record an screencast for clarification?
He can't get screen recording to work with Wayland, let's return the ticket to UNCONFIRMED for now.
But the bug is that when you double-click a closed menu (eg. File), it opens, but doesn't close.
When you double-click an open menu, then it behaves normally, first it closes than reopens.
I couldn't repro it myself, though, in Ubuntu 17.04.
Repro, but only with GTK3 backend.

The gtk3 backend is using a native gtk menubar, so it's (mostly) out of our control. Indeed I can reproduce the same with other gtk3 apps (gnome terminal, evolution).
