Nesting an unordered list in an ordered list, or vice versa via UI controls

Hi,

Recently noticed that we are no longer able to nest an unordered list in an ordered list, or vice versa using UI controls
I recall this used to be possible a while back, but it no longer seems to work.
You can still nest different types of lists by using the Markdown syntax "-" within an ordered list, the UI controls display this correctly and allow you to switch back to the main list type but can trigger the nesting again using the same controls.

Unsure if this is by design or a bug, but most of our users are not familiar with the Markdown syntax and struggle with more advanced formatting.

Using the Cloud version of Outline.
