View entire Parent Item without opening new window

In “My Work,” if a sub-item is assigned to me, I will only see the name of the sub-item. If I hover over the button to the right of the title, it will show the name of the Parent item, but when I click on it, it doesn’t show the entire Parent item along with all the sub-items under it + deadlines. The only way to see the entire Parent item and all sub-items is to click on the name of the Board that the Parent item is in which then opens a new window.

Clicking on the small button to the right of the sub-task title should show the entire parent item including all sub-items.
