With the in-application menu bar, you can click on "Help" to open a menu and then move the cursor to "File" to open that menu instead. With the plasma widget you need to click on "File" for it to open.
Urgh. Turns out this isn't easy. We only get hover events if our window has focus. The panel doesn't have focus because the menu window does. I can't think of a good solution.
Didn't I explicitly add the event listener hack to allow this? It doesn't work when the mouse is on the outer edge of the panel because of its padding, though. Here this works.
None of that eventFilter stuff seems to work here; and there's a code comment (from you) saying it doesn't. I don't understand how it would help, an eventFilter on the menu isn't going to help you get mouseEvents on the button grid. (off topic, could that eventFilter be the reason for your submenus closing issue?)
> I don't understand how it would help, an eventFilter on the menu isn't going to help you get mouseEvents on the button grid. Yes it does. It filters mouse move events and then looks whether at cursor position is a button of the menu applet and if there is, it invokes it. The FIXME comment at the top only refers to when a submenu is opened. > (off topic, could that eventFilter be the reason for your submenus closing issue?) No, I'm experiencing this issue only with decoration appmenu, not the applet.
Ah, when the menu is not at the left-most edge of the panel I can reproduce the issue.

This isn't fixed in Plasma 5.9.3.
This is not fixed for me as well (Arch Linux Plasma 5.9.4)
Not fixed for me either (Arch Linux with Plasma 5.9.5). However, the menu in your "standalone" version on github (https://github.com/kotelnik/plasma-applet-active-window-control) works flawlessly. I recommend anyone currently having the issue to build that applet from source and use it as a replacement.
If this isn't fixed for you, see the replacement QML file I posted on bug 376725 (which is really a duplicate of this one).
