Close Gap on selected clips ignores Sync Lock off for adjustment layers (right-click Ripple Delete on a single gap works)

Premiere Pro 26.3.2 (Build 2), macOS Tahoe 26.4.1, Apple M1 Ultra, 128GB RAM

This has been happening since at least 2021, across multiple versions, so it is not a recent regression.

With Sync Lock turned off on the track holding an adjustment layer, Close Gap run on selected clips (multiple gaps at once) still treats the adjustment layer as a blocker and refuses to ripple delete the clips together.

What works as expected:

• Sync Lock off on audio tracks: ignored correctly by Close Gap.
• Sync Lock off on a normal video clip track: ignored correctly by Close Gap.
• Right-click > Ripple Delete on a single gap: works whether the adjustment layer track is sync locked or unlocked.

What fails:

• Close Gap on selected clips with the adjustment layer’s track set to Sync Lock off. The setting is ignored.

Steps:

1. Sequence with clips on V1 to V4 with several gaps, and a full-length adjustment layer on V5.
2. Turn Sync Lock off on V5.
3. Select the V1 clips and run Close Gap.

Expected: V5 is ignored, as audio and normal video tracks are.
Actual: Close Gap refuses to run, or is blocked by the adjustment layer.

Workaround: drag the adjustment layer to the end of the timeline, close the gaps, drag it back.
