Level 3 menu not rendered correctly

Hi

I have noticed that with a split menu, the third level does not display correctly. The same seems to be happening on the Helium and RT Horizon templates.

The images show what is happening - the 3rd level seems to be constrained and clipped by level 2:

I have seen the same problem on other J4 & J5 sites but to check I have set up a new site (Joomla 5.0.3 and PHP 8.1.27) with just Gantry 5 (5.5.17) and Helium (5.5.17). Nothing else installed, no additional CSS and I see the same issue:

The menu looks like this:

When I click on L2 Item 5 it looks like this:

After clicking on Level 2 Item 2:

Dropdown Style: Extended
Dropdown direction: Expand right
Dropdown width: 300px

If I change the Dropdown style to Simple it looks like this:

And if I change the Dropdown width to Auto with Extended style I get this:

The result I was hoping to see was something like this:
