Can't keyframe "Render Custom Depth pass" with Sequencer.

4.12.5
When I keyframe the Render Custom Depth bool in a level sequence, it doesn’t update in the viewport when previewing or at runtime.
I’ve tested about every other rendering option and everything else appears to be working as intended.
Is there a reason I’m unable to key custom depth, or is this a bug?
Can anyone confirm this on a later engine version?

I guess it was a known issue. I’ve verified it’s fixed in 4.14.3
