Right click problem

Hello. There is a problem with right-click context menus in XFCE, still
unresolved as I see it in Mint 20.
If a menu happens to be taller than a half-height of the display AND
mouse pointer is placed within the range of the menu width to the right
display border, a right-click (tap&release) will automatically select an
item from the menu that happens to be beneath the mouse pointer at the time.
Example: my resolution is 1366x768, and while I am using Firefox it is
usual to get quite a menu when I right-click links. Lets say that its
height is 500 px and width is 250 px.
Suppose we have the X coord of the pointer (from top left corner) >
(1366-250) = 1116 px. The right edge of the menu then would be attached
to the right edge of the display.
If the mouse pointer Y coord > 500 px, then the menu will expand
entirely above the pointer and I am ok.
If the mouse pointer Y coord < (768 - 500) = 268 px, then the menu will
expand entirely below the pointer and I am ok.
If the damn pointer Y coord happens to be inside the overlap region
(which is 268 < Y < 500) then the full expansion into either direction
is not possible, so the problem arises and when I release the right
mouse, an item will be selected.
This is obviously an unwanted behaviour and I consider it as a bug (but
you may not, however). It seems there are workarounds available to me as
the end user because it is an intrinsic mechanics of XFCE, isn't it?
So, I suggest this: if (X mouse > menu width) AND (Y resolution/2 < menu
height), then expand the context menu **entirely** to the **left** of
