I've finally found the condition that causes this issue. 1. Window geometry when it opens has the top decoration snapped to the panel and the bottom of the window is snapped to the bottom of the screen. 2. Vertically semi-maximize the window by dragging the window to the left or right side of the screen. 3. Drag the window to the top to maximize the window.
It's important to note the initial window geometry and the dragging to semi-maximize. If either the top of the window is not snapped or the bottom of the window is snapped, the issue does not occur. Also, using the Ctrl-Super-Left/Right to vertically semi-maximize will avoid this issue as well.
