Cannot set start offset of items with stretch markers

This affects REAPER scripts as well. You can set the start offset to a value, but nothing happens. The only way to do really set it is with the nudge dialog or ApplyNudge.

another licecap:

The item becomes void when take start offset is greater than source length. Gluing the item causes the item to disappear completely. This is different from the behavior of when no stretch marker is present: The item simply becomes silence and does not disappear after gluing.

another another licecap:

After you delete stretch marker (after setting take start offset) the offset is transferred to source offset. 4.0s of take offset becomes 4.0s of source offset.

No sound until after 2nd stretch marker ONLY IF preserve pitch is off (when you move the first marker):

* Realtime: You get silence if you start the play cursor before take offset.
* After render: Silence is revealed.
