Smart Clips: "Duplicate" command broken

[SteveDaulton]

Describe the bug
Applying "Edit menu > Duplicate" to more than one audio clip produces overlapping clips.

To Reproduce
Steps to reproduce the behavior:

1. Generate a 10 second "Chirp"
2. Split at around 5 seconds
3. Select from around 3 seconds to around 7 seconds
4. "Ctrl +D" (duplicate)
5. Observe overlapping clips in new track

Expected behavior
The new clips should be at the same time position as the original audio.

Screenshots
If applicable, add screenshots to help explain your problem.

Additional information (please complete the following information):

• OS: Linux
• Version 3.2.0-alpha-20220115

Additional context

There are also some related serious bugs:

• replacing step 4 with split new gives incorrect result
• replacing step 4 with copy, and then paste somewhere gives incorrect result

Is this bug report specific to 3.2? I think I encountered it in 3.1.3 today (also on linux), with both the duplicate and copy/paste variants.

Here's a screenshot after duplicating; after copy/paste it looks very similar:

I think in this image, it's the third clip that's been placed on top of the first clip, instead of after the second as it should be.

Is there any sort of workaround? I know I could join the clips first, but I wanted to preserve the cut locations in order to help align the clips elsewhere in the project
