My only comment at this point is: wouldn't be simpler to always use DropdownMenu in a controlled way? Something like

const open = currentClientId !== undefined && openedBlockSettingsMenu === currentClientId;

I believe that the logic would just be simpler, and the behaviour of the DropdownMenu component more predictable (furthermore, React usually warns when this pattern is applied to input elements)

It'd be simpler in this component, but due to current usage of the BlockSettingsDropdown, a currentClientId isn't always available as a block object isn't always provided. So we currently need to support both controlled and uncontrolled in this component.

In practice, at the moment, the List View provides a block object, however the block settings menu in the toolbar doesn't (it provides clientIds for the selected blocks instead, which isn't quite the same as the concept of the block when used in the list view), so if we switch to always controlling the component, we wind up breaking the dropdown in the editor canvas:

Separately to this PR we could potentially look at refactoring other usage of the block settings dropdown to ensure a block object with clientId is always provided, and then we could have the component always operate in controlled mode.

For now, I'd prefer to try to contain the scope of this PR to the BlockSettingsMenu itself, so I think retaining this slightly complex ternary is probably a good step to go with for now, as it focuses on the main use case to solve which is with the behaviour in the list view.

This is the block of code that I'm suggesting to add some more comments about it being a temp solution..

// This is a temporary solution to work around an issue with `onFocusOutside`
// where it does not allow a dropdown to be closed if focus was never within
// the dropdown to begin with. Examples include a user either CMD+Clicking or
// right clicking into an inactive window.

Do we really mean to have the default clientId as an empty string? I can see the action is set up to handle undefined clientId and the reducer will also return a null, and those are all three different values representing "empty", which seems like an inconsistent behavior. Should we make it consistent and ultimately only go with either of them?

type: 'SET_OPENED_BLOCK_SETTINGS_MENU',

Did you mean null or undefined? The default value is null and currently we'll return undefined if a clientId is missing for some reason when dispatching the setOpenedBlockSettingsMenu() action (this feels like an inconsistent behavior on its own, so I'm commenting with it separately).

The block editor reducer is quite thoroughly covered by unit tests. A couple of simple tests could be useful to cover this new reducer subtree.

For better precision, did we mean to return the default state of null instead of undefined in that scenario?

Suggested change
return action?.clientId;
return action?.clientId ?? null;

Oh, good call, that helps give this reducer consistency with other reducers that track a client id or null 👍
