Subclips in a production behave differently than standalone

Match framing subclips back to master clips does not work if they are in separate projects in a production.

Steps to recreate

1. Import master clip to master clip project in a production 

2. Create subclips and move to a subclips project in the production

3. Create an edit in an edits project in the production & add the subclips made above

4. Match frame from sequence X2 

Expected behaviour:

Sequence should first match to subclip, then to master clip.

Observed behaviour:

Subclip does not match frame to masterclip (like it does where everything is in one project).

Added bonus:

Make one of the subclips NOT be restricted to trim region - now the 2nd match frame matches to the start of this sub clip, regardless of actual match point.
