Panel obscures the menu search box. (Xia regression?)

Bug description

Under some conditions - see 'Steps to reproduce' for detail - opening Mint's menu makes the panel obscure the menu's search box.

I managed (despite this) to get a screenshot:

The proximate cause seems to be as follows. When and only when (1) 'Force the panel to be visible when opening the menu' is false, and (2) one opens the menu with the keyboard, the menu appears too far up the screen.

Steps to reproduce

1. Have an autohiding top panel.
2. Have this menu option disabled: 'Force the panel to be visible when opening the menu'.
3. Have the pointer outside the panel-opening trigger area.
4. Open Mint's menu by using a keyboard shortcut.
5. Start typing - and do not move the pointer.
6. See that the panel drops down, obscuring one's typing - and stay's down until one clicks somewhere outside the trigger area.

Expected behavior

5 should not happen.

Cf. #12536?

Start by reproducing the Cinnamon menu and autohiding top-panel interaction with the listed settings: keyboard shortcut, pointer outside the trigger area, and search typing. Investigate the menu and panel positioning behavior under those conditions. Done means opening the menu and typing does not cause the panel to drop down over the search box.
