Short description of error
The "Show Disabled" option has no effect - disabled markers (and their paths) are shown regardless of whether it's checked or not.

Exact steps for others to reproduce the error

Open the Movie Clip Editor and load some image/video.
Add a marker.
In the "Track" tab of the Sidebar, click the eye next to the marker's name to disable it.
In the "Clip Display" popover in the header, uncheck the "Show Disabled" setting. The marker remains visible.

Actually, the marker gets hidden if it is not active.

To still show a disabled (but active) marker (even though Show Disabled is OFF) was a conscious decision from 9a9924c79c

Commit lacks the reasoning for doing so ( @Sergey ) but I assume this is all working as intended then.

Will close (but of course feel free to comment again and present a real usecase where the current behavior is blocking of some sort -- we can always reopen in such case).

The long story short: this behavior simplifies interaction with tracker in a complex shots.
Longer story below.

When you're tracking something complex, tracks might be appearing and disappearing. This is controlled by the disabled state of marker. Often you'd want to move those markers out of the way, to improve clarity at a current frame you're working on.

When you are adding new track, and start tracking, at some point tracker might give up because it can't reliably track. In this case tracker places disabled marker, and when there is no markers to track anymore the tracking algorithm stops. At that point you might decide to nudge failed markers back on their feature, and resume tracking. If selected disabled markers were hidden, such nudging would have been much more challenging from artist perspective.

Thank you for the clarification. If you have only one marker, it apparently stays active (and permanently visible) even if you deselect it, but with two markers, I could indeed get one to disappear.

The behavior isn't blocking by any means - I merely encountered it while updating the documentation and checking whether the current description is still valid or needs amending.

Active and Selected are separate states in Blender. You can have active but unselected object, for example.
