Perhaps a couple of things you could consider if you really must have the accordion (although they'll have some side effects):
Add a 'delay' to the accordion
You'd need the mouse hovered over the item for (say) a quarter of a second for it to expand. The beauty of this trick is that when the first accordion list collapses, another accordion list that the mouse may be hovered over won't be immediately opened.
You'll have to fine tune the delay duration as if it is too long, users may not notice it or get annoyed if they have to use it a lot and it takes too long.
Change it to be toggled by mouse clicks.
Lots of ways this could be done so it all depends on the use case. One quite common way is to click accordion 'button' to expand and click again to collapse. If try to open two (or more) you could have it automatically close the previously opened accordion list or allow multiple accordion lists to be opened at once and let the user collapse and expand as they please.
On another note
Visually each element looks the same – so users would not be able to tell if it is a accordion or not at a glance.
