Issue/Description:
In Tasks, items that require scrolling to access do not display the context menu when clicking the vertical ellipsis (⋮). The context menu only appears once the item is no longer inside a scrollable view.

This is observable when searching for the same item: if the search results do not produce a scrollbar, the context menu works as expected for the same item.

Version:
0.2.0

Steps to Reproduce:

Open COSMIC Tasks
Create enough items in a list to require scrolling
Scroll to an item that exceeds the view & require scrolling
Click on its vertical ellipsis (⋮)
Observe that the context menu does not appear for that item & items below
Search for the same item so that results fit without a scrollbar
Click the vertical ellipsis (⋮) again

Expected Behavior:
The context menu should open reliably for all items, regardless of whether they are inside a scrollable view.

Other Notes:

Upto item 3 the context-menu is produced as expected
4 can produce context-menu if I search for it which eliminated the need to scroll

This appears to be a libcosmic bug, if I click the menu multiple times in a scrolled item this happens:
