Can click through 'Actions' popup menu to window underneath

[viol8or-alba]

Describe the bug
When the 'Actions' popup menu appears, it mostly covers the modulation routing widget. If you click a menu item at a node over the modulation routing widget, it will toggle the node through the popup. This is in Tracktion Waveform Pro 12.

What did you try to do
Steps to reproduce the behavior:

1. Click 'Actions...'
2. Select 'Rename Patch' but make sure to click over a node in the now obscured routing widget
3. The node will be toggled

Expected behavior
Mouse events shouldn't pass through to the window below the popup menu.

Screenshots
If applicable, please add screenshots to help explain your problem.

Software (please complete the following information):

• DAW: Tracktion Waveform Pro 12
