ID 263073 - Text effect referencing clip and frame metadata on separate track fails in render, ok in Viewer

Problem summary

Customer reported version
nuke.10.0v5

Customer reported platform
10.11

Steps to reproduce

1)
open attached project in Nuke Studio10.5v1, there is a footage folder with a 12- and a 14-frame clip.

essentially it is 2 clips on one track with a gap in-between; each clip has a Text soft effect; on a separate track above is a Text effect spanning the duration of the 2 clips on the track below it

​

​

2)
In Conforming workspace, reconnect the media

3)
In Finishing workspace, double-click the 3 Text soft effects to open their panels; with the playhead on the effect, note the metadata coming from the Text nodes 

4)
select both clips and all 3 Text soft effects

5)
right-click and select Export

6)
In the Export dialog, select 'Process as Sequence' and export preset Photo-JPEG.mov

7)
Choose a project root folder to render to

8) 
Transcode by clicking 'Export'

9)
Open the .mov in Nuke or any playback app and look at the output, particularly the Text  at the clip and track level

Workaround
Unknown. 

Reproduced by support
repro'd on Nuke Studio10.5v1 
on OS 10.10.5
on Windows 7

This is a REGRESSION - problem does not happen on Nuke Studio10.0v5

Expected behaviour
when rendered, the metadata output by the Text effect on the separate track failed to show the correct clip metadata of the second track; in GUI it was correct

Actual behaviour
render should match Viewer
