ID 567170 - Keyframed Avid Effects spanning multiple Panels can be imported with the wrong Trim Animation in Flix

Problem summary:
Keyframed Avid Effects spanning multiple Panels can be imported with the wrong Trim Animation in Flix
 
This has been observed with Resize Effects, but could occur with other Effects as well.
 
Customer reported version:
Flix 6.6.2
 
Customer reported platform:
N/A
 
Steps to reproduce:
1) Download the attached Trim_Issue.aaf file, and launch Flix.
2) Create a new Sequence, and press the Editorial button to open the Editorial workspace.
3) Import the Trim_Issue AAF file.
4) Observe how the Panel's Animation in Flix has been trimmed, and does not match the duration in Avid (252 frames):

 
Expected behavior:
Animated Ref panels imported to Flix should have durations that match the corresponding section of the Avid timeline.
 
Actual behavior:
In this particular case, having an animated Resize Effect span two panels in Avid causes the Trim Animation of the Panel in Flix to not match the expected duration. The problem seems to be inherent to the original Keyframes on the Resize Effect, and it has not been possible to reproduce this issue from scratch.
 
Workaround:
If this problem occurs, deleting and then recreating the Effect's Keyframes seems to resolve the issue.
