Applications Menu doesn't show with dash-to-panel with certain monitor configurations
When using Dash to Panel and the Applications Menu extensions, sometimes when clicking on the Applications Menu, the menu will not display on the screen. This issue was triggered for me when using two monitors and setting the primary monitor to be to the right of the other. Having the same monitor as the primary but swapping the placement of the two monitors (configuring the primary monitor to be on the left side) seems to have solved the issue. When switching back to the default panel, the issue went away.
This was observed on Ubuntu 18.04
