The audio Preview in timeline disappears in nested sequences

ISSUE
There's been a problem for some time now where the audio preview in the timeline sometimes suddenly disappears in nested sequences.

STEPS TO REPRODUCE
I've found that this happens when you've created a keyframe (at least in the audio) inside of the nested sequence. 

EXAMPLE:

- MAIN SEQUENCE
In this sequence, you've got a nested sequence. Let's call it the SUB-SEQUENCE.

- SUB-SEQUENCE

In this sequence, you've got a video file and an audio file. If you add a keyframe to the audio of this keyframe, the audio preview in the Main Sequence will disappear.

EXPECTED RESULTS
The audio preview should not disappear from the main sequence when adding a keyframe to the audio file in the sub-sequence.

ATTACHMENTS

I've attached a screen recording of me reproducing the bug, where you can first see all of the audio track's audio previews. And then I go into the sub-sequence and add a keyframe in the audio file in the sub-sequence (nested sequence). And the audio preview of the main sequence disappears.
