ID 381704 - If two versions of a clip have different frame ranges, the frames will not be aligned correctly when changing versions

Problem summary
If two versions of a clip have different frame ranges, the frames will not be aligned correctly when changing versions.

Customer reported version

Hiero 11.3v1

Customer reported platform
CentOS 7

Steps to reproduce

1) To reproduce this bug, you will need a clip with more than one version (ie. test_v001.####.dpx and test_v002.1001.dpx). They will also need different frame ranges, in this example, v001 has a frame range of 992-1010 and v002 has a frame range of 1000-1010.

2) Open Hiero and import version 1 of the image sequence (File > Import File(s)...)

3) Drag the clip onto the Timeline.

4) Version the clip up (with the clip selected, press Alt+Up) and notice the frames are not aligned correctly.

Notice that the frames are not aligned correctly between the two versions. For clip v002, frame 1000 is now in the place where 992 was, it should actually be around the middle of the Track Item.

Reproduced by support

This bug has been reproduced in:
Hiero 11.3v2 - Windows 10 - Linux CentOS 7 - macOS 10.13 (High Sierra)

Hiero 11.3v1 - Windows 10 - Linux CentOS 7 - macOS 10.13 (High Sierra) - Regression

Unable to reproduce bug in:
Hiero 11.2v5 - Windows 10 - Linux CentOS 7 - macOS 10.13 (High Sierra)

Earliest version tested
Hiero 11.2v5
- This issue no longer appears in this version and has regressed

Expected behaviour
The frames should be aligned correctly across all versions of the clip. The following example shows the correct behaviour in Hiero 11.2v5:

v001 of this clip has a frame range of 992-1010

And v002 of the same clip, that starts at frame 1000 and ends at frame 1010, should then look like this after versioning up:

Actual behaviour
If two versions of a clip have different frame ranges, the frames will not be aligned correctly when changing versions.
